This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k-  turbulence model was employed. By means of SIMPLE algorithm the...

In the current research project, the thermal performance of a series of newly designed mixers has been investigated. Each mixer has two concentric cylinders comprising two annular slot flow channels around a solid cylindrical rod at the center. In each mixer, the first cylinder around the central solid rod has either spherical or pyramidal protrusions throughout the outer surface. It has been o...

Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...

nowadays, environment-sensitive smart drug delivery systems have found diverse applications in pharmaceutical science and technology. these systems can respond to the environment stimuli such as temperature, pressure, ph, light, electrical and magnetical fields and etc. they can release the proper amount of drug in human body. among these systems, special attention and much research works have ...

leather manufacturing involves a crucial energy-intensive drying stage in the finishing process to remove its residual moisture. determining drying characteristics of leather is vitally important so as to optimize the drying stage. this paper describes an analytical way for determination of the drying characteristics of leather. the model presented, is based on fundamental heat and mass transfe...

In this paper a laminar flow of water on an ice layer subjected to a slip condition is considered numerically. The paper describes a parametric mathematical model to simulate the coupled heat and mass transfer events occurring in moving boundary problems associated with a quasi steady state steady flow process. The discretization technique of the elliptic governing differential equations of mas...
