Heat Transfer Studies on Packed Bed Using Non Newtonian Fluid

Abstract

This project aims to study and compare the heat transfer characteristics for Counter-current flow and Parallel Flow through Packed Bed by determining the overall heat transfer coefficient, effectiveness, cold side efficiency and hot side efficiency for water-water system and Carboxymethylcellulose (CMC)-water system with various compositions on volume basis. In Packed Bed, the inlet temperatures of both hot and cold fluids are maintained constant. In performance analysis the flow rate of cold fluid was varied from 3 lpm to 8 lpm for both water-water system and CMC-water system. The flow rate of hot fluid was maintained constant for both water-water system and CMC-water system. In this work the composition of the CMC-water system were varied from 0.05% to 0.20% on volume basis. The experiments were carried out for both parallel and counter current flow pattern, compared and reported. A physical model was developed using dimensional analysis and fitted with the experimental data. Simulation studies were done using this physical model and compared with the experimental values. The simulation studies were found to agree well with the experimental results.
