Our team has been working on developing UPACS (Unified Platform for Aerospace Computational Simulation) based conjugate heat transfer analysis to meet such demand. It is an analysis method that solves the flow field as well as the heat conduction of the contacting solid object simultaneously. This method does not require thermal boundary condition on the contacting wall where neither adiabatic nor constant temperature condition can be applied. The temperature field inside the object, which is required in evaluation of the thermal stress, can be directly obtained. Therefore, the conjugate heat transfer analysis can be a powerful tool to deal with the heat problem in high temperature parts. In this report, advanced treatment in the turbulent models for flow analysis is installed to adapt to the wide range of flow field. Validation has been conducted for the basic flow fields for cooling problem, such as impingement cooling, simply cooled turbine airfoil and film cooling flow, to demonstrate the advantages of the proposed analysis method.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
