Reflux condensation phenomena in single vertical tubes

Modeling of A Single Turn Pulsating Heat Pipe based on Flow Boiling and Condensation Phenomena

Demand for high-performance cooling systems is one of the most challenging and virtual issues in the industry and Pulsating heat pipes are effective solutions for this concern. In the present study, the best predictor correlations of flow boiling and condensation are taken into account to model a single turn pulsating heat pipe mathematically. These considerations, result in derivation of more ...

Unsteady Flow in Vertical, Converging Tubes

INTRODUCTION The discharge ofliquids from vertical tubes with various con­ traction geometries was studied via the unsteady Bernoulli equa­ tion. The temporal variations of the exit velocity and fluid level in the tube were found from the numerical integration of nonlin­ ear differential equations. Sudden, quadratic, and exponential contraction geometries were considered. For inlet to exit area...

Studies of mixed convection in vertical tubes

The early study of convective heat transfer considered the branches of forced and free convection independently with only passing reference to their possible interaction. In fact the two are extreme cases of the general condition of "mixed" or "combined" forced and free convection where both mechanisms operate simultaneously. The present contribution aims to provide an up-to-date review of thos...
