Abstract: In this paper, the problem of optimum cross-section profile in axisymmetric Stokes flow has been discussed under the restriction of specific drag. We take up a class of bodies to be of given ...

Abstract: For determining the stochastic response and stability of a strongly nonlinear single-degree-of-freedom system using the stochastic averaging technique, the size of excitations should be small such that the response of the ...

Abstract: Flow mal-distribution inside manifolds hampers the overall efficiency of processes in industries. In supercritical boilers, improper flow of steam inside the superheater (SH) section is a common cause of thermal accidents. ...

Abstract: Degradation of surfaces of hydroturbine components caused by impact of abrasive particles carried by flowing water is a serious issue. To counteract the same, surface modification of turbine materials by the application ...

Abstract: The exergy analysis of a compression ignition (CI) engine for quantification of fuel to available energy could be the most effective tool to determine the fuel efficiency and effectiveness. During this investigation a few ...

Abstract: Cryogenic fluid entering a warm feedline absorbs heat and undergoes rapid flash evaporation leading to pressure surges, which can retard the flow inside the feedline. It may have serious repercussion in operation of the ...

Abstract: We investigate heat transfer in supercritical steam flowing in a spiral tube by conducting three-dimensional numerical simulations. The current numerical solver has been validated with the existing experimental results, ...

Abstract: Seismic safety assessment of reinforced concrete box girder bridges has received considerable attention as they are increasingly popular in modern highway systems. However, the detailed seismic assessment of box girder ...

Abstract: This paper investigates the adaptability of different Reynolds-averaged Navier-Stokes (RANS)-based turbulence models for flow behavior and thermal performance of combined multiple shell-pass shell and tube heat exchanger ...
