3.2.1 Introduction

This function group computes the characteristic Mach Number $M *$ as given in [JDAnderson1982] and [Shapiro1953] from a given mach number $M$ or in reverse the latter given $M *$ . The characteristic mach number has the following properties:

M *= 0 if M = 0 M *= 1 if M = 1 M *< 1 if M < 1 M *> 1 if M > 1

And furthermore the its most useful property:

√︄ ----- lim M *= γ+-1 M→ ∞ γ-1

The following properties are computed:
