Thermophysical Properties of Working Fluid and Heat Transfer in a Hydrogen Combustion Engine
A larger burning velocity and a shorter quenching distance for hydrogen as compared with hydrocarbons bring a higher degree of constant volume and a larger cooling loss from burning gas to the combustion chamber wall in internal combustion engines.

Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in
