Mass Transfer and Urban Problems

Computational and Experimental Visualization in Heat and Mass Transfer Problems

Validation and improvement of theoretical models and numerical results using experimental data is one of the most challenging research goals nowadays. With this objective a new experimental technique was developed and applied to the study of heat and mass transfer problems in uid ows. The method, based on a computational analysis of the colour and displacement of liquid crystal tracers, was use...

Adaptive Linearly Implicit Methods for Heat and Mass Transfer Problems

Heat and Mass Transfer in Leather Drying Process

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 tra...

Flow Analysis Heat and Mass Transfer in a Room

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...

Comaprison of Mass-Transfer Efficiencies of Scc and Structured Packing

In a previous paper, pressure drop, flooding and mass-transfer characteristics of a novel pilot-scale distillation column called spinning cone column (SCC) were presented. Here, we present the result of comparison of mass-transfer efficiencies of SCC and structured packing. Comparison of SCC and structured packing mass-transfer characteristics show that the gas and liquid-side height of transfe...
