Numerical simulation of natural convection of the nanofluid in heat exchangers using a Buongiorno model
作者：
Highlights：
• Natural convection of nanofluids in a cavity is studied using a Buongiorno model.
• By reducing the diameter of the nanoparticles the heat transfer rate increases.
• At high Ra, the distribution of the solid particles remains almost uniform.
• There is an optimum volume fraction of nanoparticles for maximum Nusselt number.
