1) Solid heated bar in a cavity
We consider a coupled solid/fluid case. A flow at given velocity and temperature profile is injected in a cavity. A solid heated bar is fixed in the middle of this cavity. The flow temperature is changing with time. The geometry and mesh are given in next figure.
The data of a simulation corresponding to the “tri” profile (in red in the figure below) is used by dynaROM™ to generate a dynamic reduced order model. Then, the model can predict the flow evolution for three other temperatures profiles: square, sqtri, sinus, defined in the following figure.
The results of these simulations are compared to the reference ones in the following videos. Only the temperature part of the field is presented.
- “Sinus” profile
- Sqtri profile
- Square profile
2) Fluid/Solid Coupled Heat Transfer
The geometry of the test case is given below.
One first case is used for learning the dynamical reduced order model :
One second case is used for prediction :
