MATHEMATICAL MODELING OF MULTIPHASE HYDROJET PUMP OPERATION

Mathematical Modeling of Surface Roughness in Surface Grinding Operation

A mathematical model of the surface roughness has been developed by using response surface methodology (RSM) in grinding of AISI D2 cold work tool steels. Analysis of variance (ANOVA) was used to check the validity of the model. Low and high value for work speed and feed rate are decided from design of experiment. The influences of all machining parameters on surface roughness have been analyze...

Mathematical Modeling of a Simulated Fixed Bed for Desalting Operation

Continue survival of the petrochemical industry in the face of advancement in processing technology must change for better performance. In doing so, the pre-treatment stage of crude, which include desalting will go a long way at improving the overall quality of the product obtained. It is in view of this that a mathematical modeling of adsorption of a fixed simulated bed for desalting operation...

Multiphase modeling of tumor growth and extracellular matrix interaction: Mathematical tools and applications

In a multiphase modeling framework tumors are described as a mixture of tumor and host cells within a porous structure constituted by a remodeling extracellular matrix (ECM), which is wet by a physiological extracellular fluid. The main focus of the model presented in this article is the description of the mechanical interactions of the growing tumor with the host tissue, their influence on tum...

Multiphase Turbulent Modeling using LES

The modeling of multiphase, turbulent flows and their dynamics has become increasingly important in many environmental, geophysical, and engineering applications. These areas require the use of models that can effectively represent both the multiphase and turbulent characteristics involved in the simulation. Due to the large increase in computational power required to both simulate multiphase a...
