The hot gas casing of the gas turbine has operated in high temperatures and thermal gradients. The structure safety of hot gas casing will be highly depend on the thermal stress. In this paper, flow and thermal stress analysis of the hot gas casing is carried out using ANSYS program. The obtained temperature data by flow analysis of hot gas casing is applied to the load condition of the thermal analysis. The thermal stress analysis is carried out the elastic-plasticity analysis. The pressure, temperature and velocity of the flow and thermal stress of the hot gas casing are presented

Spun Yarns

The technique of thermal stress analysis is discussed in terms of basic yarn mechanical properties, particularly stress relaxation, and in terms of fundamental concepts of fiber fine structure. Examples of stress-temperature data obtained by this technique are given for as-spun, drawn, and textured yarns from polyester, polypropylene, and nylon 66. Several process variables are shown to affect significantly the stress-temperature “fingerprint” of a yarn, including, for as-spun yarns: orientation, ageing, and quenching; for drawn yarns: draw ratio and drawing temperature; and for textured yarns: texturing temperature, overfeed, and dyeing conditions.
