Abstract:

Heat transfer in a thermomechanical probe operated in a noble gas is studied by computer simulation in the collisionless approximation. The study is motivated by the fact that heat transfer in the gaseous environment becomes the main factor affecting the data-reading sensitivity as the feature sizes of thermomechanical probes used in data-storage systems becomes smaller the mean free path in the gas at room temperature and atmospheric pressure. A mathematical model is constructed and implemented in software. This is employed to run a computer simulation with the aim of evaluating the data-reading sensitivity in the case of helium. The behavior of the sensitivity, the data-reading time and the energy consumption with decreasing the heating pulse duration are examined.
