The boundary layers on the duct walls were resolved with a wall distance of the first grid point of y+ ≈ 1 , while the flow condition on the walls of the outlet tubes were deter- mined using the logarithmic wall law. A large cubic outlet was constructed (not fully shown) at the ...
In addition, they found that abnormal mode-shapes appeared as a result of the fluid velocity vector contribution in the z-direction and also the upward acceleration of fluid velocity. In the study by Tubaldi et al. [72], geometrically nonlinear vibrations of thin, infinitely long rectangular ...
The curved prism segment has been divided into a series of small trapezoidal prism segments with the same cross section and its magnetic field is a vector sum of the individual fields created by each small trapezoidal prism conductor. For one trapezoidal prism conductor the magnetic field is ...
The vector potentials are selected in the transverse plane normal to the air and dielectric interface and are expanded in terms of a set of rectangular orthogonal functions. Enforcing the field boundary conditions on the perfectly conducting boundary and on the air/dielectric media interface, the ...

stream. Freestream Mach number, Prandtl number and ratio of specific heat capacity for air are taken to beM∞=2,Pr=0.72andγ=1.4respectively. Reynolds number based on the inlet displacement thickness is set asReδ∗=1500throughout. The dynamic viscosityμ(T)is computed by Sutherland’s law...
The results indicate that the variation of flow resistance parameters of shear-thinning power-law fluid often shows a nonmonotonic trend, which is different from that of water. It can be concluded that protrusion structure can effectively enhance the heat transfer of CMC solution with low pressure...
springs at the nodal points. The relationship between the displacement and the applied load for the entire structure is expressed through the following equation:(1)Ku=FwhereKis the overall stiffness matrix of the structure,uis the nodal displacement vector, andFis the force vector acting on the ...
