Summary

Fluid-structure interaction (FSI) is referred to the pressure contact of a flexible solid structure with a flowing fluid causing structures to deform. Thus, the flow field created from the altered deformed structure exerts another form of pressure on the structure. The process may repeat and produce an interrelation between the fluid pressure and structural deformation.

The application of FSI simulation is widely used in various studies such as hydro-elasticity, aero-elasticity, thermal deformation,flow-induced vibration, blood vessel,heart failure, stenosed and etc.

    A New Processing Method for the Nonlinear Signals Produced by Electromagnetic Flowmeters in Conditions of Pipe Partial Filling

    Abstract When a pipe is partially filled with a given working liquid, the relationship between the electromotive force (EMF) measured by the sensor (flowmeter) and the average velocity is nonlinear and non-monotonic. This relationship varies with the inclination of the pipe, the fluid density, the pipe wall friction coefficient, and other factors. Therefore, existing measurement methods cannot meet the accuracy requirements of many industrial applications. In this study, a new processing method is proposed by which the flow rate can be measured with an ordinary electromagnetic flowmeter even if the pipe is only partially filled. First, a B-spline curve fitting method… More >

    Abstract Paravalvular Leakage (PVL) has been recognized as one of the most dangerous complications in relation to Transcathether Aortic Valve Implantation (TAVI) activities. However, data available in the literature about Fluid Structure Interaction (FSI) for this specific problem are relatively limited. In the present study, the fluid and structure responses of the hemodynamics along the patient aorta model and the aortic wall deformation are studied with the aid of numerical simulation taking into account PVL and 100% TAVI valve opening. In particular, the aorta without valve (AWoV) is assumed as the normal condition, whereas an aorta with TAVI 26 mm for… More >

    Abstract This study deals with the interaction of blood flow with the wall aorta, i.e., the boundary of the main artery that transports blood in the human body. The problem is addressed in the framework of computational fluid dynamics complemented with (FSI), i.e., a fluid-structure interaction model. Two fundamental types of wall are considered, namely a flexible and a rigid boundary. The resulting hemodynamic flows are carefully compared in order to determine which boundary condition is more effective in reproducing reality. Special attention is paid to wall shear stress (WSS), a factor known for its ability to produce atherosclerosis and bulges.… More >

    CFD Simulation of a Bag Filter for a 200MW Power Plant

    Yukun Lv, Jiaxi Yang, Jing Wang
    FDMP-Fluid Dynamics & Materials Processing, Vol.16, No.6, pp. 1191-1202, 2020, DOI:10.32604/fdmp.2020.010302

    Abstract The combustion of pulverized coal inevitably produces dust and other harmful substances. For these reasons, the optimization of de-dusting procedure and equipments is an aspect of crucial importance towards the final goal of making this source of energy more sustainable. In the present work, the behaviour of a “bag filter” is simulated using Computational Fluid Dynamics (CFD). More specifically, three possible approaches are used, differing with respect to the level of fidelity and the partial utilization of empirical data. The outcome of these simulations is mutually compared and finally discussed critically in the light of available experimental results. More >

    Abstract Aiming at the problem that the total pressure loss of the flue of the electric precipitator of the 350 MW unit of a power plant to the inlet of the draft fan is too large, the numerical simulation software Fluent and the standard k-ε model was used to simulate the flue, the results show that the main part of the flue mean total pressure loss is derived from the confluence header and elbow. In order to reduce the loss and consider the cost of transformation, the concept of twodimensional feature surface is established, gradually proposed three sets of flue transformation… More >

    Abstract On the basis of a macro flow resistance method and the Darcy Theory, a mathematical model is elaborated to characterize the flow resistance of a bag filter serving a coal-fired power plant. The development of the theoretical model is supported through acquisition of relevant data obtained by scanning the micro structure of the bag filter by means of an electron microscope. The influence of the running time and boiler load on the flow resistance and the impact of the flow resistance on the efficiency of the induced draft fan are analyzed by comparing the results of on-site operation tests.
