Question

converging nozzle

A converging-diverging nozzle with Ae/A 3.0 is attached to a resevoir in which air is main tained at 500 kPa and 27°C. As discussed in lecture and illustrated in above film, the behavior of the flow in the diverging section and at the nozzle exit depends on the value of the back pressure, pb. As indicated in Fig. 13.12 in text, the behavior can be classified into four Regimes (I-IV), which are demarcated by pb values associated with the fl w conditions (iii), (iv), (vii). Prepare a table summarizing the following a. for each Regime and flow condition (iii, iv, vii), if throat Mach number Mt is unity b. for each flow condition, the exit pressure, pe, and exit Mach number, Me c. the range of pb values associated with each Regime d. for each Regime, if Me is k, unity e. for each Regime and flow condition if pe is pb f. indicate which case is design condition, undererpanded nozzle, overeapanded nozzle
