Research conduct investigations to implement the appropriate numerical models for the properties of nano-fluids that satisfy a wide range of experimental data, and study the effects of fluid mass to be inserted in the pipe, rotation speed of the machine, nano-particle size and nano-particle concentration on heat transfer performance of rotating cylindrical heat pipes. To solve the non-linear differential equations governing the flow of nano-fluids inside the heat pipe and the heat transfer equation, a new methodology based on particle swarm optimization (PSO) has been considered. A model is constructed wherein it is assumed that the rotation speed of the machine/pipe is high, so that the effect of gravity is negligible compared to the centrifugal force.
