CFD Analysis of Various Design Aspects in Baffle Tube Heat Exchanger

Abstract

To improve temperature difference, a computer simulation assessment for a rectangular duct with right angle confounds heat exchanger with small displacements and bewilder height was carried out. A total of 10 There were three separate two half Autocad models of rectangular shaped channel with bewilders spacing of 40 milimetre, 80 milimetre, and 120 milimetre and baffle heights of 10 mm, 12.5 milimetre, and 15 milimetre developed. The major goal of this study is to run computer simulations to see how Cu water nanoparticle affect the architecture and thermally hydrodynamic characteristics of a rectangular duct with baffles exchanger. The bottom walls of the canal, as well as the baffles, are regarded isothermal zones, whereas the sidewalls are termed regular zones. This approach employs a second derivative upwind mass and energy equation. The baffle pitch and height have a significant influence on the temperature distribution from the rectangle shaped channel  heating element, with a maximal temperature fluctuations of 9.831oC and a maximum heat transfer of 6.571 KW for baffle spacing 40 mm and height 15 mm for rectangle channel without opposite baffles. In comparison to the base design of rectangle shaped channels exchanger, the temperature difference increases nearly 1.5 times as even the width is decreased.
