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 ...

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

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.

Entropy Generation during Head-On Interaction of Premixed Flames with Inert Walls within Turbulent Boundary Layers

Entropy, 2022
The statistical behaviours of different entropy generation mechanisms in the head-on interaction of turbulent premixed flames with a chemically inert wall within turbulent boundary layers have been analysed using Direct Numerical Simulation data.

Entropy generation approach for evaluating energy dissipation and temperature rise to predict the fatigue life behaviour in magnesium alloy

Journal of Materials Research and Technology, 2023
The objective of this present study is to use entropy generation to predict the fatigue life behaviour of magnesium alloy. As the energy dissipation rate directly correlates with material degradation and increases in temperature, the entropy generation ...

Long‐Term Outcomes of Patients With Relapsed/Refractory Neuroblastoma Treated on ANBL1221: A Report From the Children's Oncology Group

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Results of COG ANBL1221 changed treatment paradigms for patients with relapsed/refractory neuroblastoma. Chemoimmunotherapy with irinotecan/temozolomide/dinutuximab is now used as both bridge therapy following suboptimal response to induction and as treatment in first relapse.

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.

Thermal Analysis in Pipe Flow: Influence of Variable Viscosity on Entropy Generation

Entropy, 2004
: Flow through pipes and heating situations find wide applications in industry. Depending on the fluid properties, temperature field in the pipe changes. This in turn results in thermodynamic irreversibility in the flow system.

Admixture Mapping Reveals Candidate Regions for Methotrexate Neurotoxicity Susceptibility: A Reducing Disparities in Acute Leukemia Consortium Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...

Entropy Generation of Shell and Double Concentric Tubes Heat Exchanger

Journal of Engineering, 2016
Entropy generation was studied for new type of heat exchanger (shell and double concentric tubes heat exchanger). Parameters of hot oil flow rate, temperature of inlet hot oil and pressure drop were investigated with the concept of entropy generation ...
