Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 9
Abstract
We studied the experimental observation and simulation for rectangular unnotched fin validated for different thermal load (i.e., 20W, 30W, 40W, 50W) .After that we also simulated different cases (i.e., 20W, 30W, 40W, 50W) based on applying different forms of constant area as an inverted notched fin. All above result of the distribution of temperature, velocity vector plot, Nussalt no. and the heat transfer coefficient, we are here to conclude that the heat transfer coefficient increased continuously in all cases but inverted triangular notched fin is giving maximum heat transfer rate. Heat transfer coefficient of inverted triangular notched fin is 7.16 W/m2°k which is highest among all. Heat transfer of inverted circular notched fin in 6.15 W/m2°k which is second highest. Inverted trapezoidal notched fin give 6.08 W/m2°k heat transfer coefficient better than inverted rectangular notched fin which give 5.67 W/m2°k heat transfer. Rectangular unnotched fin give least heat transfer coefficient of 4.66 W/m2°k, the result are for the case with 20 W load. Nusselt no. of inverted triangular notched fin is 300.02 which is highest among all. Nusselt no. of inverted circular notched fin in 268.02 which is second highest. Inverted trapezoidal notched fin give 251.28 Nusselt no. better than inverted rectangular notched fin which give 234.38 Nusselt no. Rectangular unnotched fin give least heat Nusselt no. of 192.44.These are the results for the case with 20 W load.
