Very good video. I have a question... Why you suppress the blades in the geometry configuration??? ...I thought you may suppress the cylindrical enclosure...since the cylindrical region is to indicate what will be set to a given RPM...
@MechTechSimulations17 күн бұрын
The purpose of suppressing the solid domain is to exclude it from the computation. Generally, we do not want to include solid domains in CFD analysis in most cases like this. Therefore, to remove the solid blade, we suppress it. The cylindrical domain, where the airflow exists, is mandatory for the computation

Understood what is the function of synchonising cone but how power is transmitted is not clear like previous videos
@MechTechSimulations23 күн бұрын
Synchromesh is also a constant mesh gearbox with an additional synchromesh cone. First, the male cone and the female cone come into contact. Then, the synchromesh ring engages. The synchromesh ring functions similarly to the dog clutch in a constant mesh gearbox.

There is a shortcut, in 4:10 you can factor the (-1+λ) into the expression (1-λ)(1-3λ+λ^2) -1+λ = 0 (1-λ)(1-3λ+λ^2) - (1-λ) = 0 (1-λ)(1-3λ+λ^2-1) = 0 (1-λ)(λ^2-3λ) = 0 That way, the three eigenvalues can be found momentarily and there is no need to solve a cubic equation and perform long division.

@QuantumBeatsLab3 ай бұрын
do I need to consider the cross sectional area in case of a 2D contour?
@MechTechSimulations3 ай бұрын
If that is a cylinder, we need to select axisymmetric instead of planar in Fluent's general settings. In 2D simulations, the mass flow rate is computed and reported in Fluent by considering the third axis as 1m by default. You can change this in the reference values if you have the third axis dimension.

@MechTechSimulations3 ай бұрын
Unfortunately, as far as I know, ANSYS cannot calculate thermal conductivity on its own. Instead, we must input the thermal conductivity value obtained from experimental data or reliable sources like material databases. However, once we provide the thermal conductivity along with the heat generation rate, ANSYS can generate temperature distribution results across the entire domain.

Sorry for the delayed reply. You can simply set up a pressure outlet boundary condition on that surface if you only need an opening and want to monitor variables within the domain. However, if you're also interested in understanding what happens beyond the outlet, you'll need to extend the fluid domain outside as well.
