Experimental Investigations on the Thermal Performance of a Vertical Closed Loop Pulsating Heat Pipe Using Binary Mixture of Fluids

This paper presents the experimental investigations conducted on a vertical closed loop pulsating heat pipe (VCLPHP) to evaluate the thermal performance. The values of thermal resistance and heat transfer coefficient obtained in the experimentation is used as evaluation parameters. The VCLPHP used has capillary tubes having an inner diameter of 2mm and outside diameter 3mm and bent into 5 turns...

Optimizing naturally driven air flow in a vertical pipe by changing the intensity and location of the wall heat flux

Heat transfer from the internal surfaces of a vertical pipe to the adjacent air gives rise to the air flow establishment within the pipe. With the aim of optimizing the convective air flow rate in a vertical pipe, the details of the flow and thermal fields were investigated in the present study. Conservation equations of mass, momentum, and energy were solved numerically using simple implicit f...

A Numerical Study of the Effect of Aspect Ratio on Heat Transfer in an Annular Flow Through a 270-Degree Curved Pipe.

In the present paper, a three dimensional annular developing incompressible laminar flow through 270- degree curved pipe is numerically simulated. The dimensionless governing equations of continuity, momentums and energy are driven in toroidal coordinates. The governing equations are discretized by projection algorithm using forward difference in time and central difference in space. A three-di...

Experimental and Numerical Investigations on Al2O3–Tricosane Based Heat Pipe Thermal Energy Storage

The enhancement of operating life cycle of electronic devices necessitates the development of efficient cooling techniques. Therefore, in the present work the effects of employment of Phase Change Material, in the adiabatic section of heat pipe for electronic cooling applications were experimentally and numerically investigated. Tricosane (100 ml) is chosen as PCM in this study, where Al2O3 nan...
