[Thermal Liquid library Simscape] Help for an Engine cooling model
Hey guys !
I am part of a formula student team, and decided to create a simulation and modelling department for the team, which aims to model our car in Simulink. I am pretty new to simulink/simscape, and as a first task, I wanted to model the car cooling system. The aim is to determine a required flow rates in the radiators to help the aero team to design side pods.
The cooling system follows the path : Left radiator (ambient cooled) -> right radiator (ambient air and a fan operating) -> pump -> engine -> reserve tank -> left radiator ect…
My model can be found through the drive : https://drive.google.com/drive/folders/1V4-4UYZZNaCwbORp9fOJHBTNA97NV8K8?usp=sharing
For now, it has been assumed that the engine temperature is constant at 383.15K. I have neglected the effects of the fan, as they operate only when the car is at low speed. The heat exchanger now receives moist air as coolant (so ambient air), and through a pressure source (which I guess is the pressure agains the radiator as the car is driving). The cooling curve looks better, however, as I vary the pressure source value, the coolant temperature doesn’t vary (or I can’t notice on the graph any change in temperature. (it always look like that)
Could anyone help me on that ? Not only the model displays wrong values (from testing, the coolant temperature should sit at 80°C ), but i am also looking for a way to chnaghe the pressure block source, to a volume flow rate in the radiators.
Here is a picture of my updated simplified model. To model the radiators, I have used the tutorial: from mathwork https://uk.mathworks.com/help/hydro/ug/modeling-heat-exchangers.htmHey guys !
