... cross flow velocity to the main jet velocity ratios (M = 0 to 1). The Reynolds number (Re) is varied from 5000 to 50000. Furthermore, the aspect ratio of the slot jet is also varied. The center-line distribution of Nusselt number along the crossflow direction is provided. From the present numerical...

... mm, a stage aspect ratio of 1.0, and an overlap ratio of 0.0. The diameter of the circular end plates (Do) attached to the rotor tips is 1.1 of the rotor diameter (D). All studies are performed at a wind speed (V) of 6 m/s. The variations of torque and power coefficients are estimated for all...

..., an effective specific heat technique was used to model the phase change process. Heat transfer results for smooth circular and rectangular microchannels with PCM fluid were obtained under hydrodynamically and thermally fully developed conditions. A PCM fluid in microchannels with different aspect ratios...
