The cell ratio h/w, stagnation pressure
[P.sub.2], thickness t, and cell lift coefficient CL' in the case shown in Figure 3 are 0.9, 61.25 Pa, 1 mm, and 0.55, respectively.
The wake of the Grand Prix car is dominated by a large region of stagnation pressure
deficit coupled with the counter-rotating vortex pair from the rear wing.
The reason for this is that besides reducing the stagnation pressure
on the trailing vehicle, the wake of the leading vehicle also reduces the suction pressure on the curved frontal surfaces of the trailing vehicle.
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.
The pitot tube's opening on the end reads total pressure (sometimes called stagnation pressure
), while the openings on the side measure static pressure.
The pressure is at its highest on the forward tip of the expanded bullet and that pressure is called 'stagnation pressure
The freestream Mach numbers were 0.33 and 0.64 [+ or -] 0.01, and the stagnation pressure
and temperature were 172 [+ or -] 0.5 kPa and room temperature, respectively.
The alternating mode of the stagnation pressure
is obtained again.
Unfortunately as the fan pressure ratio and fan speed are reduced, the fan design becomes more sensitive to inlet flow distortion and installation stagnation pressure
The stagnation pressure
coefficient and drag coefficient also show a complex dependence on the power law index and Reynolds number.
This means that the dynamic equilibrium is re-established when the stagnation pressure
from inside the tower equals the one from outside, at the exit level,
In this expression [P.sub.0] is the upstream stagnation pressure
; [T.sub.0] is the upstream stagnation temperature; d is the CFV throat diameter; [R.sub.u] is the universal gas constant; M is molecular weight of dry air; and C* is the real gas critical flow function for dry air--a function of [P.sub.0] and [T.sub.0].
