Summary

Welcome to the Special Issue on "Modeling and Applications of Bubbles and Droplets in Engineering and Sciences". This fascinating field spans a wide array of disciplines, including environmental science, mechanical and ocean engineering, biomedical engineering, alcoholic beverage fermentation, soil improvement, bacterial sterilization, and more. The study of bubbles and droplets in fluids is central to understanding many natural and industrial processes. Phenomena such as cavitation, bubble collapse, and bubble oscillation further illustrate the dual nature of bubbles in fluids. On the one hand, these phenomena can produce microjets that cause corrosion and severe vibrations. On the other hand, bubble oscillations generate microjets, temperature spikes, and shock waves, enabling applications in areas such as drug delivery, kidney stone disintegration, eye surgery, medical treatments, surface cleaning, and more. Droplets, whether liquid or solid, play critical roles in diverse applications, such as inkjet printing, spray cooling, fuel injection, aerosol medicine delivery, and environmental pollutant transport. Their behavior—encompassing formation, breakup, coalescence, and evaporation—poses both scientific challenges and engineering opportunities.


This issue aims to highlight the latest advancements and insights into the dynamic and interdisciplinary study of bubbles and droplets in fluids, showcasing their fundamental mechanisms and practical applications. Recent advancements in the study of bubble and droplet dynamics have introduced new tools for analyzing the fundamental chemical, mechanical, and physical aspects of these phenomena and applying them in a myriad of fields. This special topic seeks to serve as a collaborative platform, inviting researchers and scientists to present and discuss their original contributions through letters, research articles, full-length/mini-reviews, and more. Our ultimate objective is to propel the field forward by offering novel theoretical insights, cutting-edge numerical modeling, innovative simulations, and experimental revelations.

    Numerical Analysis of Pressure Propagation Emitted by Collapse of a Single Cavitation Bubble near an Oscillating Wall

    Quang-Thai Nguyen, Duong Ngoc Hai, The-Duc Nguyen, Van-Tu Nguyen, Jinyul Hwang, Warn-Gyu Park
    CMES-Computer Modeling in Engineering & Sciences, DOI:10.32604/cmes.2025.070570
    (This article belongs to the Special Issue: Modeling and Applications of Bubble and Droplet in Engineering and Sciences)
    Abstract This study presents a numerical analysis of the effects of a rigid flat wall with oscillating motion on the pressure wave propagation during a single spherical cavitation bubble collapse at different initial bubble positions. Different nondimensional distances S = 0.8, 0.9, 1.0, 1.1, 1.2 and 1.3 were considered to investigate the effects of initial in-phase and out-of-phase oscillations of the flat wall. Numerical simulations of cavitation bubble collapse near an oscillating wall were conducted using a compressible two-phase flow model. This model incorporated the Volume of Fluid (VOF) interface-sharpening technique on a general curvilinear moving… More >

    Energy Transfer during Strong Oscillations of a Spherical Bubble with Non-Ideal Gas Equations of State

    Minki Kim, Jenny Jyoung Lee
    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.1, pp. 345-366, 2025, DOI:10.32604/cmes.2025.070524
    (This article belongs to the Special Issue: Modeling and Applications of Bubble and Droplet in Engineering and Sciences)
    Abstract Spherical bubble oscillations are widely used to model cavitation phenomena in biomedical and naval hydrodynamic systems. During collapse, a sudden increase in surrounding pressure initiates the collapse of a cavitation bubble, followed by a rebound driven by the high internal gas pressure. While the ideal gas equation of state (EOS) is commonly used to describe the internal pressure and temperature of the bubble, it is limited in its capacity to capture molecular-level effects under highly compressed conditions. In the present study, we employ non-ideal EOS for the gas (the van der Waals EOS and its… More >

    Numerical Modeling of Bubble-Particle Attachment in a Volume-of-Fluid Framework

    Hojun Moon, Donghyun You
    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.1, pp. 367-390, 2025, DOI:10.32604/cmes.2025.071648
    (This article belongs to the Special Issue: Modeling and Applications of Bubble and Droplet in Engineering and Sciences)
    Abstract A numerical method is presented to simulate bubble–particle interaction phenomena in particle-laden flows. The bubble surface is represented in an Eulerian framework by a volume-of-fluid (VOF) method, while particle motions are predicted in a Lagrangian framework. Different frameworks for describing bubble surfaces and particles make it difficult to predict the exact locations of collisions between bubbles and particles. An effective bubble, defined as having a larger diameter than the actual bubble represented by the VOF method, is introduced to predict the collision locations. Once the collision locations are determined, the attachment of particles to the More >

    Abstract With oily wastewater treatment emerging as a critical global issue, porous media and shear forces have received significant attention as environmentally friendly methods for oil–water separation. This study systematically simulates the dynamics of oil-in-water emulsion demulsification under porous media and shear forces using a color-gradient Lattice Boltzmann model. The morphological evolution and demulsification efficiency of emulsions are governed by porous media and shear forces. The effects of porosity and shear velocity on demulsification are quantitatively analyzed.

    Cavitation Performance Analysis of Tip Clearance in a Bulb-Type Hydro Turbine

    Feng Zhou, Qifei Li, Lu Xin, Shiang Zhang, Yang Liu, Ming Guo
    CMES-Computer Modeling in Engineering & Sciences, Vol.145, No.1, pp. 411-429, 2025, DOI:10.32604/cmes.2025.069639
    (This article belongs to the Special Issue: Modeling and Applications of Bubble and Droplet in Engineering and Sciences)
    Abstract Bulb-type hydro turbines are commonly used in small- to medium-scale hydropower stations due to their compact design and adaptability to low-head conditions. However, long-term operation often results in wear at the runner rim, increasing tip clearance and triggering leakage flow and cavitation. These effects reduce hydraulic efficiency and accelerate blade surface erosion, posing serious risks to unit safety and operational stability. This study investigates the influence of tip clearance on cavitation performance in a 24 MW prototype bulb turbine. A three-dimensional numerical model is developed to simulate various operating conditions with different tip clearance values… More >
