Variational Iteration Method for Natural Frequencies of a Cantilever Beam with Special Attention to the Higher Modes

In this work, the variational iteration method (VIM) is used to calculate the natural frequencies of a cantilever prismatic beam especially for the higher modes of vibration. The solutions yielded by VIM are validated by comparing with the natural frequencies of the said beam for lower modes earlier obtained using analytical method and the differential transform metho

Numerical Analysis of Non-Uniform Heat Source/Sink in a Radiative Micropolar Variable Electric Conductivity Fluid with Dissipation Joule Heating

Computational analysis of radiative heat transfer of micropolar variable electric conductivity fluid with a non-even heat source/sink and dissipative joule heating have been carried out in this article. The flow past an inclined plate with an unvarying heat flux is considered. The transformed equations of the flow model are solved by the Runge-Kutta scheme coupled with shooting method to depict the dimensionless temperature, microrotation and velocity at the boundary layer. The results show that the coefficient of the skin friction and the temperature gradient at the wall increases for regular electric conductivity and non-uniform heat sink/sourc
