Abstract

The Monte Carlo method was used to calculate flow past flat Pitot tubes at angle of attack α = 0 for the following flow parameters: Mach number M∞ = 5, 10, 20, temperature factor tw = 1, 0.1, and Re0 e [0–40]. The calculations were made for two types of molecule: elastic spheres (μ ∼ √T) and pseudo-Maxwellian molecules (μ ∼ T). It was found that the pressure on the end in the Pitot tube has a strongly nonmonotonic dedependence on Re0 for tw = 0.1.
