Abstract
The main objective of the present work to perform computational fluid dynamics simulations to enhance heat transfer performance for rectangular channel with baffle heat exchanger and find the behavior of carboxymethyl cellulose in the design and hydraulic thermal performance. For that eight different three dimensional CAD model of rectangular channel with baffle spacing 100 mm, 150 mm, 180 mm and 200 mm & height of baffles are 8 mm, 9 mm, 10 mm, 11 mm and 12 mm respectively, is created with the help of design modular of ANSYS workbench. Length of rectangular channel is 600 mm, and the thickness of 1.8 mm. carboxymethyl cellulose as a working fluid is used having flow behavior index n = 0.69, consistency index m = 0.02 Pa and density 997 kg/m3, Specific heat 41000 J/kg-K. The temperature of the liquid inlet is 300 K and the temperature of the rectangular wall of the channel is taken to 267 K, the bottom wall of the rectangular channel and the baffles are calculated as adiabatic and sides of channel considered as periodic zone. For the CFD analysis with second order upwind for the momentum and energy equation is used. Results show that the maximum temperature drop of 28.99 oK due to vortex formation near baffles and maximum heat transfer of 162.601 KW for rectangular channel with baffles observed for baffle spacing 100 mm & height 9 mm. it has also observed that as the spacing reduced the heat transfer increases and the optimum height of baffle is 9 mm observed.

Keywords- thermal performance, computational fluid dynamic simulation, baffles, rectangular channel etc.
