Problem Overview

This tutorial demonstrates piston cooling simulation using thermal coupling approach between fluid and solid models. Oil enters the nozzle inlet at 100^oC with a flow rate of 4e-05 m³/s. The combustion heat flux on the piston top surface is 3000 W. The piston top ring, second ring and skirt surfaces are maintained at 130^oC, 120^oC and 110^oC respectively. Engine is operated at 3000 RPM. Figure 7.220 and Figure 7.221 shows the geometry and conditions for the piston cooling fluid and solid models, respectively.
