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 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 losses.
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].
