...Adib Bazgir; Yuwen Zhang Accessing temperature data in certain manufacturing and heat treatment processes can be a challenge. Inverse heat conduction problems (IHCPs) offer a solution, allowing us to determine temperatures in inaccessible locations using transient temperature or heat flux...

... cylindrical surface (PS) and four external micro-finned cylindrical surfaces (MFCSs), with R123 and R141b at different pressures in the heat flux range 20–100 kW/m 2 , is presented in this paper. The objective of the present study is to explore the effect of pressure, surface characteristics, and fluid...

... and a radiation sub-model. The location of the solid surface from the burner exit, primary air in fuel stream, dimensions of solid surfaces, and their temperatures have been varied to study the heat flux distributions from impinging flames. Results show that the location of the solid surface from the burner ports...

...Parimesh Joshi; Anil Kumar Patil; Manoj Kumar The application of twisted tape fins (TTFs) showed a considerable enhancement in pool boiling heat flux. The present study experimentally investigates the effect of solid and perforated TTFs on pool boiling of water by varying the twist ratio (y...

... specimen and quenchant is transient and complicated in quenching process. In this paper, a spray quenching system was utilized to quench for 7xxx aluminum alloy. The influence of spray parameters, including spray pressure and spray distance, on heat transfer behavior was examined and discussed. Heat flux...

... result in a higher heat transfer coefficient, while do not alter the distribution trend. By calculating the heat flux ratio, the reduction in the heat flux at DR = 1.5 is found to be within 20% in most areas than that of DR = 1.0 on the vane surface. Email: yaochunyi@mail.nwpu.edu.cn Email...
