In order to improve the pipe dissipating area, a kind of new pipe with grid plate is proposed in this paper. Based on the basic principle of heat transfer and energy conservation law, by finite element software ANSYS the simulation analysis of the steady-state heat transfer of the new pipeline is carried out, process of ANSYS modeling, loading and solving is introduced in detail, the distribution of temperature and stress for pipe with a grid plate is given, these can provide the foundation for the selection of the optimal diameter of the grid plate and transient heat transfer analysis of pipe.

Insulation Performance

This study evaluates the insulation performance of the PAS so as to analyze the exterior insulation system, PAS(Panel Approach System), which is fixed to the structure by conducting a mock-up test and then calculates the linear thermal transmittance of the interior insulation and PAS-applied areas through a 3-dimensional steady state heat transfer analysis so as to conduct a comparison analysis of heat performance on the interior insulation system in thermal bridge areas. According to the results of the mock-up test conducted to evaluate the insulation performance of the PAS, the thermal transmittance value measured 0.15W/㎡K which shows outstanding insulation performance when compared to the Korean outer wall standard of apartment buildings that is 0.27~0.36W/㎡K. Moreover, as a result of calculating the linear thermal transmittance of the PAS in contrast to the interior insulation system through a heat transfer analysis of thermal bridge areas, the interior insulation measured 0.851W/mK, and 0.029W/mK when the PAS was applied. Thus, the insulation performance in thermal bridge areas was reduced by 96.6% in contrast to the interior insulation when the PAS was applied.

Good Agreement

This study presents heat transfer rate and temperature distributions for the prediction of each component in an air-cooled motorcycle engines. The 3-D finite element method was used to solve the temperature field and heat transfer rate for each component (intake valves, exhaust valves, piston, piston rings, cylinder head and cylinder) of motorcycle engine when the piston is in TDC and BDC. The results shows that the fractions of heat transfer rate for each component are as follows: intake valves 11％, exhaust valves 8％, cylinder head 21％, the piston 35％ and the cylinder 25％. And the temperature measurement value is in good agreement with experimental data within 20%.
