Enhancement of heat transportation by oscillatory flow using microencapsulated phase change material suspension

Abstract

This study deals with the heat transportation by oscillatory flow using Microencapsulated Phase Change Material Suspension (MPCMS) as the working fluid. The MPCMS consists of maicroencupsulated paraffin (diameter 10 μm, melting point 32 oC) and water. Experiments were performed to measure the thermal resistance of the heat transportation tube with inner diameter of 3 mm and length of 500 mm in the MPCMS mass concentration range of 0, 1, 3, and 5 wt%. The oscillation frequency and amplitude were 1 Hz and 90 mm. As the results, the thermal resistance indicates a tendency to decrease with increasing the mass concentration of MPCMS.
