Abstract

A numerical heat transfer model of a flush-mounted hot-film probe is presented for transient air flow. The model geometry involves simultaneous heat flow in both the air and the adjacent slab wall. Two cases are considered, steady laminar flow and laminar flow with a low-frequency oscillating component. In the steady-flow case, the numerical results compare favorably with steady calibration data from the literature. In the unsteady flow case, transfer function results are consistent with literature experimental data. In both cases, agreement with the literature data is obtained by calibrating the numerical model at zero flow.
