Increasing fluid's thermal conductivity by adding solid nono-sized particles

زيادة التوصيلية الحرارية للسوائل عن طريق اضافة جسيمات بحجم النانو من مواد صلبة

Abstract

According to previous researches about nanofluids, the thermal conductivity increase with heat carrier's volume decreasing, because of increasing carrier mobility. Although the conductivity increase does not have a logical explanation through using existing theories. Therefore many researches came with different explanations using the molecular view for material plates that carriers pass through, the nature of heat transportation for the mobile particles, and the effect of forming solid crystals. The researcher have seen that the effect of heat transport due to ballistic more prevalent and more effective than that due to diffusion. In addition to the polarization effect which contribute to increase the diffusion.
