Choked flow is a phenomenon that limits the mass flow rate of a compressible fluid flowing through nozzles, orifices and sudden expansions. Generally speaking it is the mass flux after which a further …

WebChoking in change of cross section flow[edit] Assuming ideal gas behaviour, steady-state choked flow occurs when the downstream pressure falls below a critical value p∗{\displaystyle p^{*}}. That critical value can be calculated from the dimensionless critical pressure ratio equation[6] WebCritical flow is defined by the following differential equation : (2-1) and it corresponds to the maximum flow rate that can be achieved by a compressible fluid as it passes from a high-pressure region to a low … WebChoked Flow Continuing the discussion at the end of the preceding section (Boe), we investigate what happens in ... To investigate this further we return to the basic governing equations Figure 2: Variations of ﬂow properties in a nozzle and a diﬀuser. (Boe1) to (Boe5).

"Choked flow is a compressible flow effect. The parameter that becomes "choked" or "limited" is the fluid velocity. Choked flow is a fluid dynamic condition associated with the venturi effect. When a flowing fluid at a given pressure and temperature passes through a constriction (such as the throat of a convergent … See more If the fluid is a liquid, a different type of limiting condition (also known as choked flow) occurs when the venturi effect acting on the liquid flow through the restriction causes a decrease of the liquid pressure beyond the … See more The minimum pressure ratios required for choked conditions to occur (when some typical industrial gases are flowing) are presented in Table 1. The ratios were obtained using the … See more The flow of real gases through thin-plate orifices never becomes fully choked. The mass flow rate through the orifice continues to … See more All gases flow from higher pressure to lower pressure. Choked flow can occur at the change of the cross section in a de Laval nozzle or through an orifice plate. The choked velocity is … See more If the upstream conditions are such that the gas cannot be treated as ideal, there is no closed form equation for evaluating the choked mass flow. … See more The flow through a venturi nozzle achieves a much lower nozzle pressure than downstream pressure. Therefore, the pressure ratio is the … See more Figure 1a shows the flow through the nozzle when it is completely subsonic (i.e. the nozzle is not choked).
