About This Topic

Multiphase flow (with/without heat transfer) have a significant influence of the flow and heat transfer in many industrial applications such as molten metal manufacturing process, volcanos and natural hot fountains, oil pipelines, energy systems, food process and chemical process. The multiphase complexity lies in its transient nature and unpredictable transitions between various types of flow patterns such as bubbly, stratified, wavy, plug, annular, etc. This Special Issue is devoted to the recent advances in experimental and computational modelling of multiphase flow with and without heat transfer.

Open Access Review

A Review of Practical Applications of Fluid Flow and Associated Heat Transfer Modeling in Wellbores

Received: 28 March 2023;  Published: 12 June 2023;  doi: 10.21926/jept.2302019


Investigations on two-phase gas/liquid flow in pipes have been under study for nearly six decades. These studies have significantly assisted in managing fluid flow in the wellbore and surface networks, leading to the separation of phases and transmission of oil and gas into the market. This study summarizes some of the main lessons [...]

Non-Isothermal Compressible Flow Model for Analyzing the Effect of High CO2 Inlet Flow Rate on Particle Size in a Supercritical Antisolvent Process

Received: 17 December 2022;  Published: 18 April 2023;  doi: 10.21926/jept.2302016


In this work with CFD simulations, the evaluation of the supercritical anti-solvent (SAS) process for producing nanoparticles from an expanded solution of ethanol/solute in carbon dioxide is reported. The influence of the solution and antisolvent flow rates on mean particle size, the flow dynamic, and the supercritical mixture's jet velocit [...]

Analysis of Correlations for the Prediction of the Entrainment Fraction of Droplets in Gas-liquid Annular Flows

Received: 14 February 2022;  Published: 24 May 2022;  doi: 10.21926/jept.2202019


In gas-liquid flows, droplets that detach from the liquid film lining the internal walls of a pipe and merge with the gas flowing through the pipe follow an annular flow pattern. This work analyzes correlations for estimating the entrainment fraction of such droplets contained in the literature by comparing their predictions with experimental [...]

Non-Newtonian Flow in Bifurcated Piping and Arterial Networks

Received: 12 February 2022;  Published: 23 May 2022;  doi: 10.21926/jept.2202018


Flows in multi-branch piping systems are modeled for linear Newtonian and nonlinear Power Law, Bingham Plastic and Herschel-Bulkley fluids. The nonlinear models are often used to describe multiphase fluids consisting of liquid and solid phases, including cement slurries and drilling muds in petroleum engineering. Rheological and heterogeneous [...]

A Large Eddy Simulation Study of Cyclones: The Effects of Interparticle Collisions on Erosion Prediction

Received: 31 January 2022;  Published: 06 May 2022;  doi: 10.21926/jept.2202017


Cyclone separators are widely used in fluid catalytic cracking (FCC) units due to their lack of moving parts and relatively low-pressure drop. However, cyclone separators are prone to erosion-related issues, which is a major drawback. In this paper, a large eddy simulation (LES) of the particle-gas flow in a cyclone separator is investigated [...]

The Drag Forces on a Taylor Bubble Rising Steadily in Vertical Pipes

Received: 04 October 2021;  Published: 07 December 2021;  doi: 10.21926/jept.2104048


By the adoption of a drag-buoyancy equality model, analytical solutions were obtained for the drag coefficients (CD) of Taylor bubbles rising steadily in pipes. The obtained solutions were functions of the geometry of the Taylor bubble and the gas volume fract [...]
