Abstract
In the present study, a CFD-aided tuned operation of a free piston shock tunnel (FPST) was proposed. For that, a numerical method which can accurately predict characteristics of a FPST was developed by using a 4th order pointwise non-oscillatory scheme and models of the flow losses. The tuned operation condition for the FPST of the Shock Wave Research Center(SRC-FPST) at the Institute of Fluid Science, Tohoku University was estimated from the parametric calculations with the present numerical method. The experiments were conducted at the condition, in which the stagnation enthalpy and pressure were 10.6 MJ/kg and 570 atm, respectively. The test flows were observed by holographic interferometry.
