Hi everybody, my question is not properly about CFD but mainly about Fluid Dynamics itself. I have performed a RANS simulation of a round jet of methane and air and now I'd like to compare those results to some experiments. Unfortunately there aren't papers about experimental data for...

Have I posted it in the wrong category?

Hi guys, could you concretely explain me (also with a simple example) the difference between blackbody emissive power (sometimes found as e'λb) and blackbody radiation intensity (i^{'}_{λb})? and which the difference between a diffuse surface and a surface that follows the Lambert law? Thank...

Hi everybody, I'm looking for a free software (or web link) for calculation of thermodynamics properties (enthalpy,entropy,density,viscosity,etc.) of a wide range of substances.Does anyone have any suggestions about ? Thanks in advance.

Thank you everybody for all helpful answers smile:

Hi everybody,I can't understand how a reactor core is sized to be critical. I'm studing the reactor theory and I've understood how make critical a reactor with simple shapes (spherical,cylindrical,etc.) equating the material and the geometrical buckling. But it's possible, in a simple way, to...

Right,it was just what I was thinking about.My assumption of natural gas as ideal gas was just for approximate its thermophysical proprieties knowing composition of this natural gas. About this I have also another question:in evaluating power of compression I also need to find the specific work...

Hi everybody, I'm having difficulties sizing a compressor for natural gas. First,my assumption is to take natural gas as mixture of ideal gases.The compression must be between 9 and 32 bar and it starts at 45 °C. I know that volumetric flow rate must be 85000 Sm3 per day ,where I assume 15°C and...

Ok,thanks a lot for your help.I appreciated it. :smile:

Yes,I have some familiarity with thermodynamics.But I know how to represent this process on T-s chart.Instead I would understand,in case of more than 1 intercooling process, how to calculate pressure values at which intercoolers must work for minimizing specific work.Could be correct to state...

Hi everybody!:smile: I have a question about intercooling process in compressors Regarding ,for example, a mutli-stage compressor with 3 intercoolers,I'm a little bit confused about finding the intermediate pressures of each intercooler that minimize specific work.I'm able to find the...
