Flow with Heat Addition

When we add heat:

  M V p T r a h p0 T0 r0 a0 h0
M<1 ↑  M→ 1

↑ for M<g-0.5
for M>g-0.5

  ↑for M<g-0.5
for M>g-0.5
↑for M<g-0.5
for M>g-0.5
 
 

as q, s↑, more democracy!
perfect democracy when KE due to V = KE due to T, or when M=1.  This results in less interference between the particles.

Follows the changes in M

Always opposite to the variation in V just like in incompressible flow.  As the flow decelerates: conversion of KE to pressure E (or dynamic E) and vice versa, just like in a spring.

    Follows the variation in T Follows the variation in T (h=cpT) As T0 the gas expands. h02=h01+q

h0=cpT0

  Follows the variation in T0 h02=h01+q

h0=cpT0

 

M>1   M→ 1
