In this study, an analysis technique that can estimate the temperature rise and thermal deformation of the ventilated disc considering vehicle information, braking condition and properties of the disc and pad is developed. The analytical process of the braking power generation during braking is mathematically derived. The thermal energy that is applied to the surface of a disc as heat flux is calculated when a vehicle is decelerating from 130 km/h to 0 km/h with deceleration of 0.4 g. Then, the temperature rise and thermal deformation of a disc are calculated through the thermo-mechanical analysis by using SAMCEF code. The shape of the cross section of the disc is optimized according to the response surface analysis method in order to minimize the temperature rise and thermal deformation. As a result of optimization, it is concluded that the temperature rise and thermal deformation of the disc become minimum at the same condition. The hot judder analysis is carried out using the original and optimized disc to validate the optimization result.
This work is to study the performance of an ecological ventilated self-weighted wood panel used on roofs in order to get a high energy savings. With this aim, we have carried out a convective heat transfer analysis of the panel by the finite volume method (FVM). Pure conduction is found in the wo...
The aim of this study is to investigate the effect of hexagonal boron nitride (BN) particle shape/size and loading level on the thermal, mechanical, electrical properties, and morphology of styrene-ethylene-butylene-styrene terpolymer (SEBS)/poly(ethylene-co-vinyl acetate) (EVA) blends to be used...
The article considers a one-dimensional quasi-linear heat equation with a volume heat source and a nonlinear thermal conductivity. The analysis is conducted for parameter values where selfsimilar solutions of the equations evolve in an LS-regime with blowup. Heat localization is observed in this ...
In situ and post-mortem diffraction contrast transmission electron microscopy (TEM) was used to study the multiplication of dislocations during a thermal martensitic forward and reverse transformation in a NiTi shape memory alloy single crystal. An analysis of the elongated dislocation loops whic...

This article reports the possibility of detoxification of chrysotile asbestos through a low temperature heating and grinding treatment. The effect of thermal treatment at different temperatures in the range from 500 to 725 °C for 3 h on raw natural asbestos was characterized by thermal analysi...
The introduction of aluminium doped zinc oxide (ZnO:Al) as a back reflector is an important part of the light-trapping techniques in present thin-film silicon solar cells. However, the application of the sputtered ZnO:Al at the back contact often results in an S-shaped J-V characteristic and a lo...
Camelina sativa oil (CO) is characterized by a high content (up to 40 wt. %) of essential α-linolenic acid and characteristic odour and flavour. Deodorization of highly unsaturated oils requires great attention as the refining process involves thermal treatment which affects oil integrity. The p...
In the current context of global warming due to CO2 (carbon dioxide) emissions, mainly produced by power plants and road transportation, it is imperative to optimize the operation of thermal engines in general and of gas turbines in particular. This requires accurate knowledge of their performanc...
Braking is a process which converts the kinetic energy of the vehicle into mechanical energy which must be dissipated in the form of heat. ¶During the braking phase, the frictional heat generated at the interface disc - pads can lead to high temperatures. ¶This phenomenon is even more important...
