Through a Fourier transformation, the Fourier coefficients of the pressure gradient are determined, which are used for the calculation of the transient mass flowrate of fuel through injection nozzles, utilizing a special reconstruction algorithm. The theoretical background of the measurement method is ...
best state-of-the-art technique by a factor of more than 8x. We expect that even higher values of compactness factor are possible through optimization of geometric parameters like nozzle standoff distance and impinging jet diameter and velocity. Figure 4 Heat and mass transfer rate improvement of...
But to make a reasonable question out of the wording given, I have to assume it contains two errors: calling velocity of flow flow rate; failing to specify where in the nozzle the 10m/s applies. Ross891 said: Ok so considering the fact that the flow rate is 10m/s through the 0.5m...
This equation states that the rate of change of liquid level in the tank is a constant, if the flow rate in is a constant. From this we know then that the change in level must be linear function of time. We show this explicitly by separation of the variables and integration: ∫0h[t...
The matrix was applied using an HTX-M5 Sprayer (HTX Technologies), with a spray spacing of 2.5 mm at a temperature of 75 °C using a flow rate of 100 μl min−1. The distance of the sprayer nozzle was 50 mm from the sample, and a spray pressure of 10 psi with a...
Hi guys, i am doing a 3d supersonic nozzle simulation using fluent. i use a quarter symmetric geometry for simulation and give a big space outside of nozzle exit. the geometry is showed below.Paint.jpg currently my problem is the mass flow rate of simulation is much less than the res...
The effects of gas mass flow rate on flow properties in supersonic nozzle flows of two-phase mixtures have been studied numerically. It has been found that the effect of the numerical preciseness of gas mass flow rate on the flow properties obtained as the perturbations from the SAM (Specified...
The multi-solute electroplating wastewater passes through the atomizing nozzle at the upper part of the separation tower, forms the spray, conducts heat and mass transfer with the high temperature air entering from the top of the tower, and finally flows out from the bottom of the tower. In ...
The steady state, steady flow energy rate balance equation (neglecting any change in kinetic and potential energy) is Sign in to download full-size image Figure 9.10. A simple mixing system. Q˙−W˙+m˙1h1+m˙2h2−m˙3h3=0 and the similar mass rate balance equation is m˙1+m˙...
To couple the limitation by the evaporation rate at the melt and the limitation the choking inside the nozzles, a novel boundary condition is implemented based on the Hertz-Knudsen equation and the isentropic relation. The numerical simulation results are validated with experimental results. First, ...
