Abstract

PARAMETRIC OPTIMIZATION OF PULSATING HEAT PIPE BY TAGUCHI METHOD

Md. Shahidul Haque*, Adib Bin Rashid and Md. Mahbubur Razzaq

ABSTRACT

Pulsating Heat Pipe (PHP) has become one of the most promising options for passive heat transfer due to its excellent heat transfer capability, high thermal efficiency and structural simplicity. The paper presents an experimental study on the operational limit of closed-loop pulsating heat pipe (CLPHP) charged with ammonia which is consists of total 14 turns of aluminum tube with 3 mm inner and 4 mm outer diameter. A constant electric power supply of 36 W was provided to run the pulsation mechanism and experiment was carried out for three filling ratios of 0.4, 0.6 and 0.8 as well as inclination angle of 0°, 30°, 45°, 60°, 90° and 180°. Here, the heat transfer rate, thermal resistance and heat transfer co-efficient is measured to determine the performance of the PHP. Then Taguchi method is applied to analyze the effect of working parameters of the pulsating heat pipe to predict the optimum design parameters. In Taguchi method, L18 orthogonal array is selected and the best optimum parameters are identified based on main effect plot for means and signal to noise ratio plot under the characteristic of smaller and larger is the better respectively. The analysis of the Taguchi method reveals that, 60% filling ratio at 30° inclination angle, performance of the PHP is maximum.
