mach_from_pm_angle

comp_flow::mach_from

Function mach_from_pm_angle 

Source 
pub fn mach_from_pm_angle<F: Float>(pm_angle: F, gamma: F) -> F
Expand description

Mach number for a given Prandtl-Meyer angle in radians.

This function uses Newton’s method to solve for the Mach number. If this function must be called many times, it may be preferable to make a look up table with mach_to_pm_angle and interpolate those values.

§Examples

use comp_flow::mach_from_pm_angle;

assert_eq!(mach_from_pm_angle(0.4604136818474_f32, 1.4_f32), 2.0);
assert_eq!(mach_from_pm_angle(0.0_f64, 1.4_f64),  1.00000022981460310);
