Hello everyone.
I am simulating flow inside a pipe. The boundary condition is that at a pressure of 22.2 MPa, 390°C supercritical water flows in at 55 kg/h from the first inlet and 20°C water enters at 79 kg/h at the second inlet. Is there any heat energy lost in the LES model? In the k-epsilon transient model, it is consistent with the temperature calculated by the enthalpy balance. When I simulate with the LES model, the result is slightly lower than that temperature. Could you help or guide me in this matter? |
