TAGGED: jt-effect, simulation
February 1, 2022 at 5:17 amitsme_tilakSubscriber
For the past few days, I have been trying to simulate the JT effect in Fluent to observe the effect of pressure change on temperature but I am not getting any result. To tell the truth, temperature is increasing as it passes through the orifice but it is supposed to decrease. To make it more clear, I use inviscid model, energy equation and pressure inlet.
Could anyone help me to fix this? It would be a great help.February 1, 2022 at 9:43 amRobAnsys EmployeeWhat gas density are you using?
February 1, 2022 at 1:45 pmDrAmineAnsys EmployeeYou require Real Fluid Properties: so either CEOS or NIST EOS or RGP (based on NIST RefProp) in Ansys Fluent.
February 1, 2022 at 3:34 pmitsme_tilakSubscriberI am using Methane as a fluid that has specific density of 0.554
February 1, 2022 at 4:07 pmRobAnsys EmployeeAnd how does a fixed density work for the JT theory?
February 1, 2022 at 4:48 pmitsme_tilakSubscriberI am using a Density-based solver
February 1, 2022 at 5:06 pmRobAnsys EmployeeOK, and what is the material density?
February 2, 2022 at 7:22 amDrAmineAnsys Employeehow will you see JT effects using constant density? Or even using Ideal Gas EOS? Can you explain?
