Summary

This study evaluated the performance of single phase heat transfer in multiport minichannels. The experimental data was observed in rectangular multiport aluminium tubes with hydraulic diameters of 1.14 mm and 7 parallel channels, the Reynolds numbers ranges from 100 – 2400, the heat flux ranges from 3 to 10kW/m2, the working fluid is water and the inlet temperatures is 12°C. The results show that the friction factors under the effect of uniform heat flux and isothermal are both in well agree with the Hagen-Poiseuille law for laminar flow. Various heat transfer coefficient models for single phase were used to evaluate the experimental data but over predicted. A modify correlation was also developed and archived a good prediction.
