Multiphase Flows with Digital and Traditional Microflidics
Multiphase Flows Digital Traditional Microfluidics
2014/10/24
Multi-phase fluid systems are an important concept in fluid mechanics, seen every day in how fluids interact with solids, gases, and other fluids in many industrial, medical, agricultural, and other r...
Modeling of Flash Boiling Flows in Injectors with Gasoline-Ethanol Fuel Blends
Flash Boiling Flows Injectors Gasoline-Ethanol Fuel Blends
2014/10/24
Flash boiling may be defined as the finite-rate mechanism that governs phase change in a high temperature liquid that is depressurized below its vapor pressure. This is a transient and complicated phe...
Mathematical models for thermally coupled low speed flows
Low Mach number flows Boussinesq approximation
2010/9/27
In this paper we review and clarify some aspects of the asymptotic analysis of the compressible Navier Stokes equations in the low Mach number limit. In the absence of heat exchange (the isentropic re...

k-turbulence model algebraic stress model flat plate flow pipe flow
2009/10/15
Turbulent flows for flat plate and circular pipes were solved using the two equation k-" model and the algebraic stress model (ASM). The computations were carried out using the parabolic solver PASSAB...
Investigation of the Friction Coefficient in Smooth Open Channel Flows
Open channel energy loss friction factor
2009/10/14
In practical engineering, the friction coecient formulations developed for circular pipes are usually assumed to be valid for open channels and used in derivation of mathematical formulation. However...
Computation of Time-Accurate Laminar Flows Using Dual Time Stepping and Local Preconditioning with Multigrid
Dual time stepping Local preconditioning Laminar flow Multigrid
2009/10/9
A cell-centered finite volume method with explicit dual time-stepping and a low Mach number preconditioning technique is successfully applied to 2-dimensional Navier-Stokes equations for the numerical...
