Analytic solutions of a two-fluid hydrodynamic model

Mathematical Modelling and Analysis, 2021
We investigate a one dimensional flow described with the non-compressible coupled Euler and non-compressible Navier-Stokes equations in the Cartesian coordinate system.

Comparison of compressible and incompressible numerical methods in simulation of a cavitating jet through a poppet valve

Engineering Applications of Computational Fluid Mechanics, 2019
The regime of compressible flow generally refers to the super/subsonic case. However, several remarkable cases with low Mach number could not be appropriately described with the incompressible method.

A dilating vortex particle method for compressible flow [PDF]

, 2002
Vortex methods have become useful tools for the computation of incompressible fluid flow. In this work, a vortex particle method for the simulation of unsteady two-dimensional compressible flow is developed.

The simulation of the flow through the porous media and diffusible barriers

EPJ Web of Conferences, 2018
Here we work with the RANS equations describing the non-stationary viscous compressible fluid flow. We focus on the numerical simulation of the flow through the porous media, characterized by the loss of momentum. Further we simulate the flow through the

Two-dimensional compressible viscous flow around a circular cylinder [PDF]

Journal of Fluid Mechanics, 2015
Direct numerical simulation is performed to study compressible viscous flow around a circular cylinder. The present study considers two-dimensional shock-free continuum flow by varying the Reynolds number between 20 and 100 and the free-stream Mach ...

Scalar transport in compressible flow

, 1996
Transport of scalar fields in compressible flow is investigated. The effective equations governing the transport at scales large compared to those of the advecting flow are derived by using multi-scale techniques.

Development of High-Fidelity Numerical Methodology for Prediction of Vehicle Interior Noise Due to External Flow Disturbances Using LES and Vibroacoustic Techniques

Applied Sciences, 2022
A pleasant and quiet cabin in driving a car is one of the most critical factors affecting a customer’s choice in a market. As the traditional noise sources such as power trains become less, the relative contribution of aerodynamic noise to the interior ...

A Compressible Formulation of the One-Fluid Model for Two-Phase Flows

Fluids
In this paper, we introduce a compressible formulation for dealing with 2D/3D compressible interfacial flows. It integrates a monolithic solver to achieve robust velocity–pressure coupling, ensuring precision and stability across diverse fluid flow ...
