The paper presents the results of air flow research around the rotorcraft. The studies focused on the measurement of the air flow velocity based on particle image velocimetry. According to the ...

Key highlights The article shows how changing pressure tap configurations—corner, flange, vena contracta, radius or pipe taps—directly affects the flow measurement output. It cautions against blindly ...

A new technique is proposed to estimate the frequency dependence of the relative conductivity of copper plates with multi modes of the balance-type disk resonator using two pairs of dielectric plates ...
