"> Waste heat recovery is very important, because it not only reduces the expenditure of heat generation, but also it is of high...

The aircraft environmental control system (ECS) is a critical aircraft system, which provides the appropriate environmental conditions to ensure the safe transport of air passengers and equipment. The functionality and reliability of ECS have received increasing attention in recent years. The heat exchanger is a particularly significant component of the ECS, because its failure decreases the sy...

A significant amount of heat is wasted in manufacturing process, electricity generation, chemical and industrial process. Recovery and reuse of this energy through storage can be useful in conservation of energy. In the present study, a double pipe type heat exchanger has been designed and fabricated for low temperature industrial waste heat recovery using phase change material (PCM) paraffin w...

Given the rapid progress in the electronics industry, the thermal management of electronics components becomes an important and serious issue. Natural and forced cooling are often deficient. One possibility for heat dissipation for high heat flux is using loop heat pipe. A loop heat pipe (LHP) is a two-phase device with extremely high effective thermal conductivity that utilizes pressure differ...

This paper describes experimental investigations on convective heat transfer in counter flow double pipe exchanger under transverse vibration for single-phase with twisted tape insert the inner tube. Experiments were conducted inserted twist ratio from 7 to 17, amplitude 23 69 mm, frequency 20 100 Hz and Reynolds number (Re) changing 10710 21420. A maximum gain of 91% Nusselt (Nu) was obtained ...
