Second law analysis of coupled conduction–radiation heat transfer with phase change

Entropy generation analysis as a design tool—A review

“…Few studies on local entropy generation analysis due to radiation are available, but most consider quite idealized cases involving rectangular enclosures or slabs [159][160][161][162]. More complex systems involving combined radiation and convection heat transfer were studied in [163,164].…”

Solving inverse problems of radiative heat transfer and phase change in semitransparent medium by using Improved Quantum Particle Swarm Optimization

“…Before retrieving the Stefan number St through measuring the boundary temperatures, we need to investigate the sensitivity coefficient with respect to St. Set the perturbation as D = 0.5%, and vary the Stefan number in the interval [0. 1,10]. The other parameters are set the same as above.…”

“…The search space of the inversion parameters can be set as St 2 [0. 1,10] or/and N 2 [0.01, 1], respectively. The retrieval results of these algorithms with no measurement error are shown in Table 4.…”

“…Laser heating semitransparent medium has received great attention in the last two decades [1][2][3][4][5][6][7][8]. Since the phase change involves complex thermal physical processes, the temperature is depends on multiple physical mechanisms.…”

Finite-volume method for solving the entropy generation due to air natural convection inΓ-shaped enclosure with circular corners

“…This efficiency loss is related to the entropy generation, which exists in all heat transfer and fluid flow processes. The optimal design criteria for thermal systems by minimizing their entropy generation have recently been a topic of great interest, especially in the fields related to geometry of a duct, natural convection in enclosure has gained attraction of many researchers [11][12][13][14][15][16][17][18]. It seems that, this mentioned literature field is surprisingly scarce about the numerical problems with curvilinear solid boundary shape.…”
