The simultaneous heat and mass transfer by natural convection around a hot body in a rectangular cavity is investigated numerically. The cavity is filled with air and the ratio of body's length to enclosure's length is ...

In this paper, the effect of a magnetic field on natural convection flow in a nanofluid-filled inclined square cavity has been analyzed by Lattice Boltzmann method (LBM). The cavity is filled with water and nanoparticles ...

The importance of the external flows around the airfoils got serious when the airplanes with high velocity crashed due to passing the critical Mach number. Those events caused to become clear the significance of the effects ...

Here, the higher order approximation of forced Duffing equation is studied. First, using the renormalization group method, the modulation equations of Duffing equation in the case of primary resonance is determined. The ...

In this paper, ongoing studies to investigate nonlinear ordinary differential equations (ODE) are extended by presenting a new concept in non-dimensionalization process. This concept is illustrated with a practical example ...

In this numerical study, energy separation analysis of a Ranque-Hilsch vortex tube (RHVT) has been investigated for different conditions such as operation of machine under applying different inlet gases. The utilized gases ...

Due to demands for the economical operations of power plants and environmental awareness, performance control of a boiler-turbine unit is of great importance. In this paper, a nonlinear multi input-multi output model (MIMO) ...

An analytical study using Variational Iteration Method (VIM) is carried out in order to investigate the vibrations of electro-statically actuated double-clamped and simply-supported micro-beams. Effects of applied voltage ...
