11.3.1 Problem Overview
This tutorial simulates the heat conduction and convection between hot fluid (air) and cold fluid (coolant) in a Exhaust Gas Recirculation (EGR) cooler. Figure 11.50 shows the geometry and conditions for the cooler simulation.
The properties for the EGR cooler for air, coolant and metal is defined in the table below:
| Properties | Material | ||
|---|---|---|---|
| Air | Coolant | Metal | |
Density ( ) in kg/m3 |
1.1766 | 1000 | 8030 |
Viscosity ( ) in Pa-s |
1.853e-05 | 0.001 | |
Conductivity ( ) in W/m-K |
0.4 | 16.2 | |
| Capacity in J/kg-K | 1005 | 3739 | 500 |
