Absorbing Layer

An axisymmetric laser beam, moving with constant speed, heats a thin infrared absorbing layer sandwiched between two plastic sheets. We use a simplified theoretical model to study the three-dimensional unsteady temperature field produced by the moving laser beam.

Transient Thermal

The paper took the piston of 620 single-cylinder engine as an example,a finite element model of piston was built with the help of ANSYS software. Than to calculate temperature field and and quick cold start conditions respectively[1]. Through the periodic transient thermal analysis, temperature fluctuations on the surface of the piston were derived, which indicated that the surface contacted with gas was the main temperature fluctuation area. The max temperature fluctuation can be up to 20 ° C and the wild fluctuation occurred in a distance of 2 mm from the surface of the piston. Temperatures of the piston went up according to exponential rule during the course of quick cold start, Extreme temperature fluctuations will generate huge quasi-static thermal stress.
