Week-7 : Converting a detailed engine model to a FRM model
Converting a detailed engine model to a FRM model
Aim:
- To Explore tutorial number 9 and write a detailed report (50 marks)
- To Build FRM Model for following configuration using FRM builder approach (50 marks)
- Bore 102 mm stroke 115 mm CR 17
- No of cylinder 6
- CI engine
- Twin Scroll Turbine
- GT Controller
Introduction:
FRM is a physical engine model that is designed specifically to run fast.When simulation speed is of high priority then GT power engine models can be simplified into FRM's using a standard conversion process.
FRMs can be achieved by two means,
- Decreasing the simulation time step size
- Decreasing the sub volume
Detailed Engine model:
FRM:
Building FRM model - 6 cylinder
FRM Model:
Case setup:
By default, GT creates 25 cases, where the RPM is varied gradually from 4000 RPM to 2000 RPM, BMEP is varied from 4 bar to 17 bar and target boost pressure is varied from 2 bar to 2.8 bar. A sample of the case setup is shown:
CASES (9-17) :
CASES (18-25) :
