Analysis of Effect of Heat Pipe Parameters in Minimising the Entropy Generation Rate [PDF]
Journal of Thermodynamics, 2016 Heat transfer and fluid flow in the heat pipe system result in thermodynamic irreversibility generating entropy. The minimum entropy generation principle can be used for optimum design of flat heat pipe. The objective of the present work is to minimise the total entropy generation rate as the objective function with different parameters of the flat ...

Predicting Entropy Generation Rates in Transitional Boundary Layers Based on Intermittency
Journal of Turbomachinery, 2006 Prediction of thermodynamic loss in transitional boundary layers is typically based on time-averaged data only. This approach effectively ignores the intermittent nature of the transition region. In this work laminar and turbulent conditionally sampled boundary layer data for zero pressure gradient and accelerating transitional boundary layers have ...

A mathematical model for entropy generation in a Powell-Eyring nanofluid flow in a porous channel
Heliyon, 2019 The continuous generation of entropy leads to exergy destruction which reduces the performance of a physical system. Hence, entropy minimization becomes necessary.

Leakage Evaluation by Virtual Entropy Generation (VEG) Method
Entropy, 2017 Leakage through microscale or nanoscale cracks is usually hard to observe, difficult to control, and causes significant economic loss. In the present research, the leakage in a pipe was evaluated by the virtual entropy generation (VEG) method. In virtual
