Use of spike on a hemispherical body changes the flow fi eld and hence the aerodynamic drag. Computational studies have been made to obtain the fl ow fi eld around a hemispherical body with spikes at a hypersonic Mach ...

This investigation presents the characteristics of Cattaneo-Christov heat flux model for the boundary layer flow of Burgers' fluid model. Instead of simple Fourier's law of heat conduction, we presented the Cattaneo-Christov ...

One of the important functionality of liver cells is ammonia detoxification and urea production. In this study, a numerical model of urea cycle in hepatocytes have been developed. Navier Stokes along with convection equations ...

Variations in loadings of rolling contact components lead to a change in contact forces between surfaces. These forces are the main cause of rolling contact damages such as fatigue. Residual stresses are a major issue in ...

In the present study, the effective parameters of centrifugal pumps are investigated using the EFAST Sensitivity Analysis (SA) method. The SA is performed using GMDH type artificial neural networks (ANN) which are based ...

Based on optimal Latin hypercube design for computer experiments, blind Kriging surrogate model and sequential quadratic programming method, the optimal design of the aerodynamic configuration of a 30mm tubular projectile ...

In the current paper, numerical simulations of Fluid structure interaction (FSI) of a SP (Surface Piercing) hydrofoil are conducted in order to study the influence of elasticity on the initial water entry ventilation. Using ...

A novel spatial parallel manipulator designed to assemble diagnostic instruments in SG-III is introduced in this paper. Firstly, resorting to screw theory, mobility analysis of this manipulator is investigated. Then the ...

With an ability to mimic the human behaviour, humanoid robots have become a topic of major interest among research fellows dealing with robotic investigation. The current work is focussed on the design of a novel navigational ...

In this paper, the general analysis of two-dimensional steady-state thermal and mechanical stresses for a hollow thick cylinder made of functionally graded piezoelectric materials (2D-FGPMs) is developed.The general form ...
