“…Moreover, the verified numerical model is tested for furnace structure optimization. The appropriate boundary conditions in the corresponding numerical model are limited by Krishnaraj et al [13] to optimize the geometry of the combustion chamber. The 3-D Navier-Stokes equations are adopted to solve the combustion simulation, and the feasibility of the CAE model is determined by using the control equations in the finite element modelling and finite element analysis software.…”

To promote the full combustion efficiency of a body cremation furnace during cremation, the temperature and velocity of cremation furnace in the process of body combustion are simulated by finite element model. Firstly, the simplified finite element analysis model of cremation furnace and its finite element software is introduced in this study, and then the flow model, heat transfer model, and combustion model needed in the heat transfer process are described. According to the requirements of the finite element model, the mesh generation process of the cremation furnace model and the numerical solution method are presented. Finally, the model used in this study is verified by the test and simulation results. The results show that the method is reliable. Besides, the design parameters of the temperature part and the combustion speed part of the furnace under six different working conditions are analyzed to further optimize the structure of the furnace. The results of this study provide a good theoretical basis for cremation equipment and promote the development of China's cremation industry.

“…Hence, typical temperatures during this process may rise as high as 2273 K, thus accounting for the thermal stresses on components within and around the engine is critical. Typical ambient temperatures within the compressor ranges between 473 K and 1000 K [41] for the low-temperature creep behaviour of titanium. The thermal interaction for the bearing housing was further examined in Abaqus (Figure 8).…”

In evaluating emerging technology, such as additive manufacturing, it is important to analyse the impact of the manufacturing process on efficiency in an objective and quantifiable manner. This study deals with the design and simulation of a bearing housing made from titanium alloy (Ti6Al4V) using the selective laser melting (SLM) technique. The Finite Element Analysis (FEA) method was used for assessing the suitability of Ti6Al4V for aerospace application. The choice of Ti6Al4V is due to the comparative advantage of its strength-to-weight ratio. The implicit and explicit modules of the Abaqus software were employed for the non-linear and linear analyses of the component part. The results obtained revealed that the titanium alloy (Ti6Al4V) sufficiently meets the design, functional and service requirements of the bearing housing component produced for aerospace application. The designed bearing is suitable for a high speed and temperature application beyond 1900 K, while the maximum stress induced in the component during loading was 521 kPa. It is evident that the developed stresses do not result in a distortion or deformation of the material with yield strength in the region of 820 MPa. This work provides design data for the development of a bearing housing for AM under the technique of SLM using Ti6Al4V by reflecting the knowledge of the material behaviour under the operating conditions.

“…Also to reduce the pollution and traffic level Delhi government introduced an odd-even system in which the odd-numbered vehicles have to be driven on a particular day and even numbered vehicles on the other day. Also, several researchers focused to improve the efficiency of IC engine [11,13], some tried with alternative fuels [7][8][9], some with combustion chamber [10,12] and many with an intake system of IC engine [5,6]. A country like India cannot immediately implement the future technologies like Electric Vehicles (EV) and Hydrogen Fuel Cell.…”

The populace in the global scenario has drastically increased in the past decades. Due to this situation, the necessity of transportation also escalated which simultaneously raised the pollution levels. Nowadays the populace commonly prefers their individual vehicles rather than public transport system. This made the automotive manufacturers to come up with new technologies and to compensate the stringent norms introduced by several countries. Internal Combustion engine has been serving the world more than a century and plays a vital role in the means of transportation. Many types of research were made to enhance the efficiency of IC engines by the use of alternative fuels, alteration of the intake parameters, stroke variation, usage of alternative materials etc., At present scenario of IC engine, the efficiency ranges between 35 – 50 % based on the technology used. If more efficient IC engines are used it would meet the demand of depleting fossil fuels. Such engines may prevent the demise of fossil fuels. Thus our project deals with the prospect to discuss the phenomenal changes and effects occurring on IC engine when the working fluid is enriched oxygen.
