how to use glow plug in diesel engine simulation using converge
hello Sir,
i want to use glow plug in my diesel engine simulation.If anyone used it before and run the simulation in converge,kindly help me (or) if you have any idea,how to use glow plug, kindly suggest. i tried with certain things such as assigning glow plug as stationary boundary of wall type with certain temperature,but it did not work. can i able to model glow plug as source/sink model? |
Hi;
It depends on how you want to simulate the glow plug. There are two approaches that I can think of:
Let me know if you have more questions. |
Dear sir,
Thanks for your suggestion As per your suggestion,I tried 1st approach where the glow plug is always on & the temperature of the glow plug is maintained at 1373 K. Though the spray touches the glow plug but there is no change in temperature of spray after heating it.so it results in fuel to be unburned and combustion does not start. I would like to know that why surface ignition of fuel is not happening though the glowplug is maintained at very high temperature. Thanking You Kasinath Panda |
Kasinath,
Are you using a wall film model and if so, is a film forming on your glow plug boundary? How much of your injected liquid fuel is evaporating currently? Best regards, Tristan |
