... secondary width (w 2 /W) are kept constant at 0.29 and 0.4, respectively. A maximum heat transmission of 3.14 times that of the base model is achieved for the transverse ribs with gaps having non-dimensional pitch and height of 9.76 and 0.044, respectively, at Re = 18,000. In the parametric range...

... studies. The time-independent heat transfer equations for EAT air and RBSAH rocks and air are obtained by making the time derivatives of the respective expressions to 0. Moreover, the volumetric heat transfer coefficient between air and rocks in the RBSAH is assumed to be infinitely large, i.e., h...
