The automotive industry is facing demand for increased specific engine performance and lowest possible engine weights. Likewise, weight reduction is also an ongoing objective in the aerospace industry. Targets such as these are pushing designers toward the limits of material properties and heat treatment.

Quenching is a common heat treatment technique used in the production of cast or otherwise-produced metal components. In particular, the immersion or direct quenching process is a widely adopted procedure in the automotive and aerospace industries to minimize the formation of undesirable thermal and transformational gradients, which may lead to increased distortion and cracking.

AVL FIRE™ M offers state-of-the art modeling functionality in the field of quenching. Various heat treatment approaches can be simulated: direct quenching in water or oil and air quenching. The structure and the quenchant fluid are simulated simultaneously, where the time and space resolved temperature distribution within the solid is thereafter applied as an input for Finite Element Analysis (FEA) of stresses and deformations with any standard FEA tool.

Webinar Outline

The webinar will outline the simulation approach for direct quenching featuring a realistic aluminum cylinder head. CFD and FEA results will be presented. The methodology will be explained as follows:
Step 1: Problem formulation
Step 2: Definition of domains; fluid side vs. solid side
Step 3: Single step multi-domain meshing
Step 4: Multi-material setup in FIRE™ M
Step 5: CFD simulation results
Step 6: Results transfer to FEA
Step 7: Stress results
