The flow field used is a generalization of the well known Couette flow solution of steady flow, in which one wall is at rest and the other wall oscillates in its own plane about a constant mean velocity. The solutions is subject to two boundary conditions that corresponds to the heat transfer and thermometer problems. The exact solutions of the Couette flow are compared with the approximate solution of the flat plate boundary layer flow in terms of the wall characteristic values at high frequencies.

“…Risso et al [4] analysed the dilute gas Cou-ette flow theory and molecular dynamics simulation. Debashish Sircar et al [5] discussed the flow and heat transfer in a micro-channel gas-liquid couette flow. The unsteady and steady velocity profile for couette flow was presented and solved exactly using the numerical method by Rihan [6].…”

Unsteady couette flow of a gas between two parallel infinite plates have been studied in this paper. We proposed a new transform technique called Elzaki transform. Analytical solution is obtained for the equation of motion by this method. Although the Elzaki transform have a close connection with the Laplace transform, Elzaki transform is easy to employ and has got several advantages over Laplace transform method.

Abstract-Compared with the conventional gas turbine, the micro gas turbine has the advantages of small size, light weight, and high power density energy. The application prospect is very broad in the future. However, lots of traditional cooling designs cannot be applied to the disks at the micro scale, which makes the heat transfer of such a disk system a major problem. In this paper, a transient experimental method is proposed to investigate the local heat transfer on a rotating micro disk with a diameter of 8 mm by measuring the temperature on the disk with an infrared scanning radiometer. The heat transfer of a single rotating micro disk is compared with the theoretical analyses when the rotating Reynolds number is low. The rotation speed which is measured using a high precision acceleration sensor based on the vibration signals ranges from 20000rpm to 110000rpm. The results show that heat transfer of the micro disk is in good agreement with the theoretical analyses, which proves that the method is effective for the micro disk with high rotation speed. Moreover, the choice of the time interval in the transient method has no influence on the results.
