In this paper, the free convective heat transfer of nanofluids in a square cavity is simulated using numerical method. The angle could be changed horizontal axis from 0 to 90 degrees. exposed under constant magnetic field. Two opposite walls are cold and warm, rest insulated. On hot wall, there two fins with same wall temperature. equations were discretized by finite volume method (FVM) then so...

AIM The objectives of this study were to assess the influence of four different kinetic cavity preparation devices on cavity preparation taking into account tip angulation, internal tip diameter, and distance to the dental substrate. The dental topography itself was also evaluated after the use of these devices. METHODS AND MATERIALS Quantitative parameters using pertinent statistical tests a...

We study light propagation in arrays of weakly coupled nonlinear cavities driven by an inclined holding beam.We show analytically that both discreteness and inclination of the driving field can dramatically change the conditions for modulational instability in discrete nonlinear systems. We find numerically the families of resting and moving dissipative solitons for an arbitrary inclination ang...

To study the mixed convection flows in a square double lid-driven cavity with various inclination angles, a numerical method based on the finite volume method is used. In this investigation Al2O3/water nanofluid with particle diameter of 47 nanometers in different solid volume fractions have been utilized. Flow is obtained by the top and bottom walls, which slide in opposite direction at consta...

Numerical study on the effect of inclination angle with sinusoidal heating on top moving lid in two-dimensional square cavity is investigated. The top lid is heated sinusoidally while the bottom wall is maintained at cold temperature. The vertical walls are insulated and the cavity is filled with water. Finite volume method and SIMPLE algorithm are employed to solve the dimensionless governing ...
