The two-phase flow is treated numerically by combining the rate equation with a volume-of-fluid algorithm. Unsteady calculations of cavitating flow in a converging鈥揹iverging passage and in a channel with a triangular obstacle show cyclically developing cavitation zones. The capability of this ...
In a supersonic flow, the velocity increases and the pressure decreases with increasing nozzle cross-sectional area. This process of expansion is the means through which high Ve is obtained. Although the thrust equation suggests that additional thrust can be obtained when the exit pressure is ...
Orifice, Nozzle, and Venturi Flow Meters: Principles, Calculations & Data The orifice, nozzle and venturi flow rate meters makes the use of the Bernoulli Equation to calculate fluid flow rate using pressure difference through obstructions in the flow. In a flow metering device based on the ...

Under these conditions, a nozzle should have a converging shape if a continuous increase in velocity is desired since by virtue of the continuity equation ρvF = const, the area F of the nozzle cross section must decrease in inverse proportion to the rise in velocity. However, with a ...
The mass flow parameter (MFP) is a variable that determines the rate at which mass is flowing through the nozzle and is given by the equation: (4) Here,is the mass flow rate through the nozzle,TOis the stagnation temperature, andATis the area of the throat, which, in the case of the...
In the order to analyzed the Ansys fluent software and solved the flow process of the convergent-divergent iteration nozzle. Standard nozzle equation manually calculated and compared with analyzing the results.doi:10.1080/01430750.2018.1517683R Ramesh Kumar...

In the present study, 2 kN and 2 kgs−1 were considered as thrust and total mass flow rate respectively as a part of the theoretical design. Then, CAD software was used for nozzle design and afterwards, validation was carried out using a CFD tool. Three fuels (methane, methanol, and ...
orifice of the nozzle 10, or the outlet end 36 of the insert throughbore 32, can also be readily calculated given a constant flow rate and a desired discharge velocity. Using the sam flow rate formula given above, Doappears in such equation as follows: ##EQU3## Where: Q=flow rate-(...
