This artcile is concerned with thermal buckling and thermal induced free vibration analyses of PCPs (perforated composite plates) with simply supported edges applying a mathematical model. The stiffness and density of PCP are defined locally using Heaviside distribution functions. The governing equations are derived based on CLPT. The present solution gives reasonable results in comparison with...

The dual fuel engines at part loads inevitably suffer from lower thermal efficiency and higher carbon monoxide and unburned fuel emission. This work is carried out to investigate combustion characteristics of a dual fuel (dieselgas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. The authors developed software in ...

in this article, thermal stability of beams made of functionally graded material (fgm) is considered. the derivations of equations are based on the one-dimensional theory of elasticity. the material properties vary continuously through the thickness direction. tanigawa's model for the variation of poisson's ratio, the modulus of shear stress, and the coefcient of thermal expansion is...

Abstract A multiplicity of simulations is required to optimize systems with thermal transient processes in the presence uncertain parameters. That why model order reduction applied minimize numerical effort. The consideration heat radiation and convection parameter-dependent transfer coefficients results a nonlinear system many inputs as these loads are distributed over whole surface limiting a...

The thermal shield (TS) system of ITER plays the role of reducing thermal loads to the cold structures that operate at 4.5 K. This paper presents the results of the detail design of TS, which are the design of joints, design of cooling panels. The results of structural analysis and thermal analysis to support the detail design are also reported. The detailed design of joints is done to satisfy ...

Analyses of the effects of service conditions on the distribution of residual stresses in railroad commuter car wheels are presented. Novel software has been applied to estimate the effects of service conditions on the as-manufactured state of these wheels. Contact loads resulting from wheel and rail interaction and thermal loads from on-tread braking are considered. Results indicate that conta...

The energy consumption by heating, ventilation, air conditioning, and refrigeration systems forms a large portion of the total energy usage in buildings. Vehicle fuel consumption and emissions are also significantly affected by air conditioning. Air conditioning is also a critical system for hybrid electric vehicles and electric vehicles as the second most energy consuming system after the elec...

Hypersonic flight introduces extreme heat loads into the leading edges of a vehicle. Determining these loads is challenging. It requires accounting for the aerothermodynamic features of both the flow and thermal state of the surface. These features can be influenced by pressure and viscous effects, real-gas and low density effects, inonization, radiative heating, surface-radiation cooling, and ...
