An impingement cooling on a flat surface by using circular jet with longitudinal swirling strips

Natural convective performance of perforated heat sinks with circular pin fins

“…More than 2 h were required to reach a steady state condition. In addition, details of the flow visualization experiments can be found from a previous study by Wen and Jang [19].…”

Heat Induced Separation in Upward Impinging Jet Flows Experimental Verification and Underlying Mechanism

“…In this section, first, the velocity comparison is made between the experimental and the computational results, and then the computed Nusselt number is compared with a previous study by Wen and Jang (26) .…”

“…Therefore, to further check the accuracy of the computation, the computed Nu stag is compared with the following correlation by Wen and Jang (26) : results. As the applicability range of this correlation does not allow the Reynolds number of 600 to be directly compared, a special computation is carried out with Re inlet = 750.…”

Numerical Simulation of the Heat Transfer from a Heated Solid Wall to an Impinging Swirling Jet

“…The swirl angle of the slots can be varied in order to have jets with different swirl intensity levels. This is a commonly extended way of giving swirl to impinging jets in heat transfer applications, as can be seen in Huang & El-Genk (1998), Lee et al (2002), Wen & Jang (2003) or Ianiro et al (2010). On the other hand, Angioletti et al (2005), and for Reynolds numbers ranging between 1E3 and 4E3, present turbulent numerical simulations of the impingement of a non-swirling jet against a solid wall.…”
