Special Issue Information

Dear Colleagues,

With the development of technologies, thermal management has been an important sector in industries which considerably affects the relevant industrial processes. For example, the ever-decreasing size of chips results in a large thermal load which, if not properly managed, will lead to the degradation of the performance and life of chips. In addition, battery systems in electric vehicles are facing serious thermal issues which need to be overcome. Further, thermal protection has attracted much attention in the field of aerospace due to the heat release of combustion and aerodynamic heating. Therefore, developing and studying thermal management solutions is essential for the high and secure performance of equipment. This Special Issue aims to demonstrate advances in thermal management from quite broad perspectives, e.g., phase change materials, phase change heat transfer, impingement jet, microfluidics cooling, or heat pipes. Experimental and numerical studies are both of interest. Both research and review papers are in the scope of this Special Issue, which is open access for researchers and engineers. Potential topics include but are not limited to:

  • Innovative thermal management technology and design; 
  • Theory, methods, and applications of enhanced heat transfer technique; 
  • Trends and prospects in boiling/condensation and heat pipes; 
  • New trends in phase change materials; 
  • New insights into film cooling, transpiration cooling, active regeneration cooling, spray cooling, etc., usually used in aerospace; 
  • Challenges and research trends of microfluidics cooling; 
  • Advances in impingement jet and combined cooling mode.

Abstract
Based on the shear stress transfer (SST) k-ω model, Ffowcs-Williams and Hawkings (FW–H) equation, and Lilley sound source equation, the flow and sound field of high-temperature and high-pressure steam ejectors are simulated. The entrainment performance, near-field sound source, and far-field noise [...] Read more.
Based on the shear stress transfer (SST) k-ω model, Ffowcs-Williams and Hawkings (FW–H) equation, and Lilley sound source equation, the flow and sound field of high-temperature and high-pressure steam ejectors are simulated. The entrainment performance, near-field sound source, and far-field noise of the steam ejector are discussed. The influences of working parameters including the primary steam pressure, the secondary steam pressure, and the back pressure are analyzed. The results show that under the design conditions, the steam ejector has two shock waves and three sound source regions. A shear layer at the boundary of the first shock wave generates the Sound source-I, and the flow separation at the boundary of the second shock wave causes the Sound source-III. The Sound source-II is located near the mixing chamber wall and the sound pressure levels around the ejector depend on the distances from the Sound source-II. In terms of the entrainment performance, with the increasing primary pressure or the decreasing secondary pressure, as the driving pressure difference of the secondary steam decreases, so does the entrainment ratio. As the back pressure increases, the entrainment ratio firstly remains constant, and then rapidly decreases when the back pressure exceeds the critical value at pb = 5.5 MPa. In terms of the noise characteristics, the sound pressure level and the intensity of the second shock wave have a positive correlation. When the primary or secondary pressure increases, the sound pressure level increases. Moreover, with the increasing back pressure, the sound pressure level firstly decreases, reaches the minimum of 98.2 dB at the critical back pressure, and then slowly increases. Full article
