Abstract

This paper proposes advanced approach able to calculate the gas properties with the temperature of binary gas mixture using the diffusion-based diameter and investigates the performance of thermal flying control for different temperature and fraction ratio at head disk interface. It is found that because of the combined effects of mean free path, thermal conductivity and viscosity, the heat transfer coefficient increases with the increase of fraction of ratio, while it decreases with the increase of temperature reversely. In addition, the pole-tip protrusion increases substantially with increase of the fraction ratio. And in higher temperature, it linearly decreases more.
