Statistical and Simulation Analysis on Dimple Configurations Performance of Heat Dissipation

This paper presents an investigation on cooling effect and flow structure of the spherical dimple configuration during air Aluminium surface. It is prominently known that applying dimples profile causes enhancement in heat transfer over a plain A three level Box-Behnken response surface methodology was performed to find correlation between input output variables. total 17 different combinations these inputs were throughout experiment. The variable be investigated namely: diameter 10 - 14 mm, orientation angle 60°- 90°, airflow velocity 16 18 m/s observe time. block heated 60°C cooled down by at room temperature. ANOVA used identify significant each parameter. CFD software as simulation tool analyze Reynolds number associate with rate support statistical findings. Based result, all parameters are found significantly dominated velocity. Staggered arrangement improves 63% flat increment will increase which then shortening
