Automotive Cooling System
Performance optimization of an automotive heat exchanger using Sherpa's method (HEEDS)
Nowadays simulation can be used at different levels of the development process and has demonstrated in many cases its ability to reduce both time and cost for studies: prototypes, mock-up and tests can be reduced to a limited number of pre-selected solutions after a numerical study.
Cylinder head temperatures are critical for understanding engine performance and durability. Accurate predictions of head temperatures are difficult due to the amount of physics interacting with the head. These interactions such as heat release due to combustion, valve heat transfer and friction, internal and external cooling, and oil splash cooling all contribute to head temperatures. To predict head temperature, a conjugate heat transfer (CHT) analysis integrating all of the interactions was performed.
