The Effect of Hot

A number of recent research projects sponsored by a range of industrial gas turbine and aero-engine manufacturers attest to the growing interest in hot-streak physics. This paper presents measurements of surface and endwall heat transfer rate for a high-pressure (HP) nozzle guide vane (NGV) operating as part of a full HP turbine stage in an annular transonic rotating turbine facility.

Kppen Climate Classification System

2019/10/24Zone B is divided into categories related to regions such as hot, arid deserts (Zone BWh); cold, arid deserts (Zone BWk); hot, arid steppes (Zone BSh); and cold, arid steppes (Zone BSk). Climate zones C and D are broken into categories based on when the dry seasons occur in the zones, as well as the coldness of the summer or the warmth of the winter.

Numerical investigations on hot

A transient global numerical model has been carried out to simulate the multi-crystalline silicon growth process by the directional solidification method using CGSim 15.1. A two dimensional axisymmetric model was used. The conductive, convective, and radiative heat transfer problems were coupled with our model and these problems were solved iteratively using the finite volume method. In the

Hydrogen embrittlement in metals

Using the numerical calculation of structures, residual stress and hydrogen diffusion when welding, it is possible to predict the cold crack resistance of complex components. Solutions allow users of thermal manufacturing processes, e.g. welding and heat treatment, the ability to address cold crack safety in the development phase when designing constructions.

Calculation for tensile strength and fracture toughness of

2018/3/29The 3-p-b numerical test reaches peak load as the loading is up to 380th step and at this moment the crack growth length just exceeds the fracture process zone (Δa fic) as Fig 16(c) illustrated. With the continuation of the quasi-static loading, the macro-cracks show instable propagation and eventually lead to the failure of the granite samples as shown in Fig 16(d) .
