# OS-E: 5000 Conjugate Heat Transfer Analysis (TFSI) of Inline-4 Engine Head with OptiStruct and AcuSolve

The Conjugate Heat Transfer Analysis of a cylinder head to evaluate temperatures in the engine block by taking into account the coupling effect with the fluid domain.

## Model Files

Before you begin, copy the file(s) used in this example to
your working directory.

## Model Description

Initial temperature and flow rate is applied for the fluid domain. Temperatures and HTC in
the cylinders (convection is applied on the structure domain) that can result from a
combustion analysis.

**FE Model**- Element Types
- CHEXA

The linear material properties are:

**MAT1**- Young’s Modulus
- 21500 MPa
- Poisson Ratio
- 0.3

## Results

Review the temperature contour on the structure and fluid domain, as shown in Figure 2.

Check the pressure drop and the flow uniformity in the fluid domain, as shown in Figure 3.
