This paper presents optimal design on wireless pressure micro-sensor based on surface acoustic wave (SAW) reflective delay line.
A cost function (including costs of the heat exchanger based on surface area and power consumption to overcome pressure drops) is the objective function, which is to be minimized.
A comparison of our proposed model versus published ones (although published models are based on surface data while our new model is based on down-hole data) shows similar results in terms of accuracy in predicting dew point pressure values.
However, later that day, a broad low pressure area had developed along axis of the wave, based on surface observations about 118 mile southeast of Cozumel, Mexico.
Some are not readily distinguishable based on surface markers alone.
Moreover, predicting the airfoil self-noise based on the surface pressure difference appears not to be generally applicable at higher angles of attack because the radiated sound is only partly due to classical trailing-edge noise mechanisms.
Drag coefficient was calculated based on integration surface pressure distribution, flow field and a reference area.
The DNS data are then used to investigate whether the approach of determining tonal noise radiation based on the surface pressure difference, as done in the classical trailing-edge theory of Amiet, yields satisfactory results for finite thickness airfoils subject to mean loading effects.
For the flat edge flap, two noise prediction methods based on unsteady-surface-pressure measurements are evaluated and compared to measured noise.
