Experimental results were compared with simulation results of the mixed flow, plug flow, cross-flow, and counter-current mathematical models.
This paper presents a numerical study of heat and mass transfer in indirect evaporative air coolers with four air flow patterns: parallel-flow, counter-flow, cross-flow and regenerative.
Two hot split-film probes in constant temperature mode were used to measure velocity fluctuations in main-flow, cross-flow and radial-flow directions, thus allowing a 3D characterization of the model's flow field.
Local current distributions for a PEMFC with serpentine flow field and three different flow arrangements including co-flow, cross-flow, and counter-flow arrangements for the anode and cathode streams are investigated along with the effect of flow channel orientation.
The mathematical models developed were validated against published experimental data presented in Appendix A. It was established, that heat and mass transfer processes in the wet channels of counter-flow, cross-flow and regenerative indirect evaporative coolers are characterized by creation of two particular heat and mass transfer zones.
Different heat exchanger configurations, including counter flow and cross flow heat exchangers are modeled and verified.
In further simulations the model was applied to investigate parallel flow, counter flow and cross flow conditions along with inlet geometry variations for the reformer.
The simulation model predicted the temperature distribution based on the cross flow fan speed, cross flow fan position and channel design of the aspirating cooling system.
The acceptable breakwater length and crest elevation were determined by taking account the maximum cross flow speed and cross flow influenced zone in addition to the construction cost.
The results for flow across bundles of woven hollow fibres may be compared to analogous results for flow in cross flow heat exchangers.
The 3D-flow regime of a cross flow filter with horizontal rotating discs was examined.
