Motivated by this, we compared the characteristics of the hot jet using six different nozzles, including profiles of velocity, Mach number
, vorticity, species concentration, pressure and temperature distributions, as well as shock structures for the C-D nozzles.
The static pressure rise is achieved through the ramming effect of the air; the increase in Mach number
results in increase in static pressure and static temperature with the loss of stagnation pressure due to the presence of shock waves.
Mellenthin, "Evaluation of blended wing-body combinations with curved plan forms at mach numbers
up to 3.
In a jet with fixed exit flow conditions, reduction of the Mach number
entails controlling convective velocity and controlling the medium surrounding the instability wave.
Figure 9 depicts the BER performance under different Mach numbers
and incident frequencies when the initial SNR is fixed at 40 dB.
is one of the critical parameter in the gas atomization process.
Three different test rigs were used to carry out the tests using boundary conditions that achieve more or less flow similarity regarding Reynolds number and Mach number
Because of the Mach number
range over which the airplane flies, the spikes must move to keep the shocks in the right place.
Wanner in  and Mattingly in  have presented different empirical equations that were able to predict the maximum thrust force for various altitudes and Mach numbers
The findings confirm that, at high Mach numbers
like those of the shocks surrounding supernova remnants, quasi-parallel shocks can become considerably more effective electron accelerators than previously thought.
This phenomenon is similar to the bomb bay instability that occurs at certain Mach numbers
when the aircraft bomb bay door is opened.
The direct specific excess power values computed by the display were then plotted versus their respective airspeeds and Mach numbers
for the piper Saratoga and the X-30 respectively.
