130R Power failure

Come on guys, I need an answer .... I need a flow figure. I have looked into the boundary conditions of the supersonic nozzle CFD analysis and realise that the nozzle inlet conditions were establish by only 3 parameters (Media, Pressure and temp.) But, I can change that for "Inlet Volume Flow" or "I...

130R Power failure

Yes Raymond, My previous posting was in answer to your discrepancy. What I am saying, is that the previous simulation was done using only the following conditions :"Gasious Propane", "225 psig." and "1200 °F" as Nozzle Inlet parameters, assuming that the CFD program knew what would be the flow of g...

130R power failure

Hummmmm..... The only thing I could do is double check the boundary conditions, make sure the data is correct. What I could do also... is to replace the actual Nozzle inlet data, wich is : Propane gas under 225 psig. @ 1200 °F, by an inlet flow condition wich would be, Propane gas Flow, temp. and p...

130R power failure

Okey Guys, CFD simulation of the Gluey Nozzle in its own intake stack @ 700 psig./1200 °F is over. I will build the repport as soon as I get Viv feed back about what should be included in the repport and what should be left aside. Then.... we will analyse and compare.

139R power Failure

Hi Dave, Basically, what you have to do when looking a the document is put your attention mostly on the images as far as plume chape and flow patern is concerned. If you want to do calculations, you will need to put your attention in the last pages, wich include the surface area data (Flow, speed, t...

130R Power failure

Okey guys, Let try something ... Let see if I can post a picture. How want to see my pressureJet at Max Power. We did a test yesterday and Pat took a picture. Look.... Bye the way ... I am still trying to figure out how to transfer the repport of the Supersonic Nozzle analysis. Cya, Luc ...............

130R power failure

Ouupppssss....

Made a mistake in my previous post and question.
The comparision is between the supersonic nozzle @ 225 psig.
and the Regular nozzle (Gluey one) @ 700 psig.

After all, this is what we are trying to achieve, match the gluey nozzle condition.

Cya .....

130R power failure

Okey Guys, CFD simulation of Raymond's supersonic nozzle is complete. Now, If only I can get a way to transfer the file to Viv, so he can post it, then you will be able to see it. I will try tonight using my own Internet account. Furthermore, I think it should be important to run the Gluhareff Nozzl...

130R power failure

Okey ... Update, I just scraped 66 hours of calculation. I stoped the calculation, thinking I could setup the program to continu using a symmetry of the stack, but guess what .... Heinnnnnnnnn...Wrong think to do. But, .... this simulation was getting nowere because the program had to much to calcul...

130R power failure

Good morning guys ... And Hi Raymond, Yes, mu CFD can do symmetry boudary conditions. I did not go that in first place, because I wanted to give you all, a total simulation results. But now that you mention it, I will do it this way. After the entire weekend, the computation is still not complete .....

130R Power Failure

Here Raymond,

A #D view of the stack it self. You can also see the 4 surfaces and the entire assembly is the computational domaine.

I hope the setup will suite our needs.

Cya,

130R power failure

Hi Raymond, Here ... I have attached a picture showing you were the numbers will come from. But, between them, you will see colors and vectors that will give an idear of the speed, temp, flow and pressure. Boundary Condition details : Source Surface = 225 psi @ 1200° F Surface 1 = Atmospheric, 14.6...

130R power failure

Man.... I am alusinating .... One minute I see a question about line and tank pressure and by the time I answer it .... Poufffff .... Don't see it anymore. Mannnn ... I need some sleep. This thing is strating to posess me.... Okey guys, the supersonic Nozzle simulation as been pushed to next week. I...

130R power failure

That an easy one..... The answer is NO .... They will always remain equal. Welll, considering you dont have 12,000 feet of tubing between. Even more, if the pressure would start to raise, you would them, start to pressurize you tank. And why Am I absolutly positive about that? ... Simple, I just ran...

130R power failure

Shit ... I got your answer to late. I have already started the simulation and it is almost complete but I think I will miss some details, like the plume shape at the end of stage 1 and what is induce in stage 2. You have to understand that these simulation take ALOT of time and CPU resources. When m...
