Conjugate heat transfer for cylinder head

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.

Performance optimization of a heat exchanger

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.

CFD-aided design of mixers for the urea injection

The performance of a Selective Catalytic Reduction SCR systems in a modern Diesel engines is strongly related to the urea-water solution injection system, to vaporization of liquid droplets, decomposition of urea vapor to ammonia (NH3) and mixing of the NH3 vapor from the urea injector to the SCR catalyst inlet. To improve the evaporation and the mixing of urea vapor with the exhaust gas, passive flow mixing devices (mixers) are commonly adopted in SCR systems.
