Oblique shock angle calculator

Oblique Shock Relations Perfect Gas, Gamma = , angles in degrees. The gas is assumed to be ideal air. If the deflection is too high, or the Mach too low, a normal shock occurs. Compute compressible aerodynamics properties using isentropic, normal shock, or oblique shock relations.

The oblique shock problem has an additional degree of freedom in specifying the problem.

If the analysis is of an oblique shockwave, enter an angle in the appropriate box and select that angle by checking the checkbox.

When shock waves are inclined to direction of flow it is oblique shock wave.

Find Pressure, Density, Temperature Ratio. Isentropic Flow Relations Calculator computer the pressure, density and temperature ratios in an isentropic flow to zero velocity and sonic conditions. You can also select Mach angle . Msin (β − θ) has replaced M2. Therefore in order to calculate Mfor an oblique shock the following steps should be followed. For any root (tanβ)k is written . The total flow after the oblique shock can also be supersonic, which depends on the boundary layer and the deflection angle.

The Simple Calculation Procedure. Methods of calculating the shock relations are organized in the class ObliqueShockRelation . To obtain the relations of density ( ρ ), pressure ( p ), and . Mach number and the flow deflection angle. INPUT: M= Turn angle (weak shock), Turn angle (strong shock), Wave angle , M1n. Determine the velocity components Vr and Vtheta immediately . Such configurations seem sometimes at first glance not related to the detached shock issue. Consider, for example, a symmetrical suction section in which the deflection angle is just between the maximum deflection angle and above half of the maximum deflection angle.

In this situation, at least two oblique shocks occur . Calculate the angle of the reflected shock wave to the wall Φ. Unlike an oblique shock , the bow shock is not necessarily attached to the tip of the body. Leave the Theta-Beta-Mach diagram behind to quickly get precise shock wave values.
