Summary
Heat transfer and fluid flow are fundamental phenomena in nature and engineering. Many aspects in production and daily life are closely related to heat transfer and fluid flow processes. Modeling and simulation of heat transfer and fluid flow are significant for a wide range of scientific and industrial applications at various spatial and temporal scales, with increased interests in recent years.
Along with the development of computer industry and the advancement of numerical methods, significant advances have been witnessed in modeling and simulation of heat transfer and fluid flow. Solid foundation in both hardware and software has been established to study the processes because of its importance in reducing production costs, discovering new phenomena and developing new technologies, etc. However, accurate modeling and efficient, robust simulation of complex heat transfer and fluid flow still remain challenging.

Abstract Simulation of fluid flow in the fractured porous media is very important and
challenging. Researchers have developed some models for fractured porous media. With
the development of related research in recent years, the prospect of embedded discrete fracture model (EDFM) is more and more bright. However, since the size of the fractures in the
actual reservoir varies greatly, a very fine grid should be used which leads to a huge burden
to the computing resources. To address this challenge, in the present paper, an upscaling
based model is proposed. In this model, the flow in large-scale fractures is directly
described…

Abstract The earth to fluid pipe (ETFP) system has been widely applied to various energy
engineering. The numerical model of the heat transfer process in the ETFP system with a
shallow-buried horizontal or a deep-buried vertical U-shape pipe adopted in practical
engineering was established and the model distinctions were pointed out. The comparison
of the thermal performance between the two types of ETFP system under various schemes
was conducted on the basis of numerical prediction. The results showed that the thermal

Abstract It is important to determine the insulation thickness in the design of the
buried hot oil pipelines. The economic thickness of the insulation layer not only
meets the needs of the project but also maximizes the investment and environmental benefits. However, as a significant evaluation, the environmental factors
haven’t been considered in the previous study. Considering this factor, the mathematical model of economic insulation thickness of the buried hot oil pipelines is
built in this paper, which is solved by the golden section method while considering the costs of investment, operation, environment, the time value of money. The

Abstract In micro-manufacturing, roughness is unavoidable due to the tolerance
of micro-machining methods. Roughness in microchannel could have a significant
influence on flow and heat transfer since the size of microchannel is very small. In
our work, roughness is modeled as a superposition of waves. A simple Fourier
series method is proposed to construct the rough surface. With this method,
roughness is constructed on the bottom of the rectangular microchannel which
has a hydraulic diameter of 0.5 mm. Two important parameters during roughness
construction, triangulate size and correlation length are studied under the same
relative roughness 1%. Results show that flow…

Abstract Structure of porous media and fluid distribution in rocks can significantly affect the
transport characteristics during the process of microscale tracer flow. To clarify the effect of
micro heterogeneity on aqueous tracer transport, this paper demonstrates microscopic
experiments at pore level and proposes an improved mathematical model for tracer transport.
The visualization results show a faster tracer movement into movable water than it into bound
water, and quicker occupancy in flowing pores than in storage pores caused by the difference of
tracer velocity. Moreover, the proposed mathematical model includes the effects of bound water
and flowing porosity by applying interstitial…

Abstract CO
2 flooding has been widely studied and applied to improve oil recovery from low
permeability reservoirs. Both the experimental results and the oilfield production data indicate
that produced oil components (POC) will vary during CO
2 flooding in low permeability
reservoirs. However, the present researches fail to explain the variation reason and rule. In this
study, the physical model of the POC variation during CO
2 flooding in low permeability
reservoir was established, and the variation reason and rule were defined. To verify the
correctness of the physical model, the interaction rule of the oil-CO
2 system was studied by

Abstract Accidents involving natural gas leakage and dispersion pose a significant
threat to human life and property. This threat is especially relevant at the street
intersection at which dense buildings, heavy traffic flow, and complex underground pipe
networks meet. Scholars have conducted numerous studies on gas leakage and dispersion,
but investigations of natural gas leakage and dispersion at the street intersection of a
building group are not in-depth. In this paper, we presented a three-dimensional (3D)
physical model based on the Computational Fluid Dynamic (CFD) methodology to study
the natural gas leakage and dispersion at the street intersection of a building…

Abstract A finite volume method based unstructured grid is presented to solve
the two dimensional viscous and incompressible flow. The method is based on
the pressure-correction concept and solved by using a semi-staggered grid technique. The computational procedure can handle cells of arbitrary shapes, although
solutions presented in this paper were only involved with triangular and quadrilateral cells. The pressure or pressure-correction value was stored on the vertex
of cells. The mass conservation equation was discretized on the dual cells surrounding the vertex of primary cells, while the velocity components and other
scale variables were saved on the central of primary…

Abstract The Ensemble Kalman Filter (EnKF), as the most popular sequential data
assimilation algorithm for history matching, has the intrinsic problem of high computational
cost and the potential inconsistency of state variables updated at each loop of data
assimilation and its corresponding reservoir simulated result. This problem forbids the
reservoir engineers to make the best use of the 4D seismic data, which provides valuable
information about the fluid change inside the reservoir. Moreover, only matching the
production data in the past is not enough to accurately forecast the future, and the
development plan based on the false forecast is very likely…

Abstract In the present study, the thermal performance of metal foam heat sink was
numerically investigated by adopting the local thermal non-equilibrium (LTNE) model
and local thermal equilibrium (LTE) model. Temperature field distributions and

Abstract The application of vortex generators in tube-finned heat exchangers is very
universal. The vortex generators can generate secondary flow, and as we all know
secondary flow can obviously strengthen heat transfer. To use vortex generators much
more efficiently in the circle tube-finned heat exchangers, the intensity correlation study
between secondary flow and heat transfer is needed. 22 different structures of circle tubefinned heat exchangers were numerically studied, including the plain fin cases and the
cases with vortex generators. In addition, the influence of fin spacing, transverse and

Abstract Pulse excitation or vibration stimulation was imposed on the low permeable
formation with cracks to enhance the production or injection capacity. During that
process, a coupling of wave-induced flow and initial flow in dual-porous media was
involved. Researchers had done much work on the rule of wave propagation in fractured

Abstract The hydraulic fracturing is a nonlinear, fluid-solid coupling and transient
problem, in most cases it is always time-consuming to simulate this process numerically.
In recent years, although many numerical methods were proposed to settle this problem,
most of them still require a large amount of computer resources. Thus it is a high demand
to develop more effificient numerical approaches to achieve the real-time monitoring of
the fracture geometry during the hydraulic fracturing treatment. In this study, a reduced
order modeling technique namely Proper Generalized Decomposition (PGD), is applied
to accelerate the simulations of the transient, non-linear coupled system of hydraulic…
