RISSelection of Materials and Design of Multilayer Lightweight Passive Thermal Protection System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A methodology has been established aiming to design a lightweight thermal protection system (TPS), using advanced lightweight ablative materials developed at the NASA Ames Research Center. An explicit finitedifference ...
Numerical Re-examination of Chilton–Colburn Analogy for Variable Thermophysical Fluid Properties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Chilton–Colburn analogy is very helpful for evaluating the heat transfer in internal forced flows. The Chilton–Colburn analogy between the Chilton–Colburn j-factor for heat transfer, jH (St·Pr2/3) and the Fanning ...

Entropy Generation in Laminar Forced Convective Water Flow Due to Overloading Toward the Microscale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this theoretical study, a fully developed laminar convective water flow in a circular tube is “convectively overloaded” toward the microscale, by decreasing the tube diameter below 1 mm. The entropy generation rate ...
Size Effect on Thermal Characteristic of Tubular Heat Exchanger at Miniscale and Microscale
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The scope for the heat transfer enhancement in the tubular heat exchanger is high due to its unique property of having two separate convective heat transfer coefficients. The variation of diameter and annular space has a ...
