130R Power failure

Heyyy Guys, I just had a good idear ... Now that we know the performance of the Gluhareff nozzle with a gas suplly at 225 psi and 1200°F. I will run a CFD simulation of the 2 evaporator coils at 3600°F, with liquid propane supplied at 700 psi. and see at what temperature the propane come out with....

130R Power Failure

Okey Guys, The Nozzle simulation is done, but for some reason I can't post it on this forum. It is a 900K word document with image. So, I will send a copy to Viv, since I have his Email and Viv, see if you can attached the repport to a new post message so all of the guys can benefit from it. Also, t...

130R power failure

Okey guys, I have started the CFD programs for the Nozzle, intake stack and engine. First, I have started with the full assembly (Nozzle, intake stack and engine) but the program took 41 minutes just to complete the meshing. So I have decided to run this in 3 steps. Step 1. Will be the nozzle it sel...

130R power failure

Nope Viv, Our CFD program is a thermodynamic and fluid mechanic software that will only consider, gas velocity, temperature, pressure, flow and others. It will not consider the accoustique or the combustion process. That why it is useless to run the entire engine. I will just run the tree stages to ...

130R Power failure

Viv,

To your last question. For us, it is impossible to do.

The only way we could acheive that, is running the engine in a CFD program. Wich I will probably do....soon.

Regards,

Luc

130R Power failure

Hi Dave, First, I live close to Montreal and I think we are 5 to 6 hours apart. As for a smaller nozzle, that could probably change thing but not bigger. Bigger would probably mean less speed, wich is not desirable. As for quiting, It is not that I am ready to quite, but if we come to a dead end, of...

130R power failure

Okey guys, You know ... It is a shame that we are not living in the same city or working together ... I would have LOVE to work with you Viv and Dave. As for the nozzle size, Viv is correct Dave. Nozzle flow is limited to orifice size and liquid propane suply pressure. If you have 32 liter/minute go...

130R power failure

Okey,

This is what a projection graphic gave me as for the thrust vs nozzle pressure, using what we already know. The results are interesting ... Hummmmm.... Viv ... Not crazy for deduction ... Hummmmm.

130R Power failure

Okey Viv, I follow you on that theory, wich I think is not crasy at all ... Only one question ... Why is the manual I got when I purchased my first engine, there is a graphic clearly showing "Nozzle Pressure at 165 psi vs Thrust at 130" for the "R" version (Rond intake). Are you suggesting these gra...

Preesure jet 130 R power failure

Goode day guys, Okey, for the recording, I will see what I can do for that. The problem is not the recording and the PC it self. It is to bring the equippment outside or to the engine and we have no laptop, but I will see what we can do. As for were the pressure reading is taken, well the meter is a...

130R power failure

I hear you, But sorry for the recording ... We have no such equippment here and the budgets for develloping this engine or bying more equippment is coming close to be empty. If the solution is to be found ... It must not be, it must not be an expessive one. We are starting to think that we have cove...

130R power failure

Okey, As for the question for the meetering orifice ... He he he ... We Also have tried them all. We tried .040", .060", .063", .078" (Gluey Specification), .090", .100" and .125". And it changes nothing. Doing that, you will have a few pounds, more or less, but no big difference. I told you guys .....

Gluhareff 130R power failure

Okey Guys .... I am back with more results. I will separate de results in steps. The steps will be "Start-up", "Warm-up" and "Max Power". The test were done in a hudge test cell and the ambiant temperature was 65°F. Start-Up: Propane pressure = 50 psi. Thrust indicated = 17 pounds Propane Temperatu...

Okey .... I have ordered 3 thermocouple capable of 2000°F. Probe #1 will be for fuel temperature before the coils Probe #2 will be positioned in the engine combustion chamber and between the coils, for coils physical temperature. Probe #3 will be position inside the nozzle cavity, were Eugene use t...

Hoooo ... Bye the way. The temperature mesuements at tail pipe while engine warm-up was 1950°F The temperature mesuements at tail pipe while engine at full power was 1750°F Ambiant temperature was 19°F It is very difficult to measure real nozzle temperature without disruting the flow pathern and ...
