Abstract A thermal model is developed to describe the electrical response of a new thermal flow sensor, the pyroelectric anemometer (PA), as a function of the laminar flow rate. For low Reynolds numbers ( Re ), i.e., Re ≤ Re c , the PA response is proportional to Re . For Re > Re c , the PA response is proportional to . The critical Reynolds number, Re c , is a function of the gas's thermophysical properties, the thermal excitation frequency, and the spacing of the measuring electrodes relative… CONTINUE READING
