An approximate generalized method for laminar, transitional and turbulent boundary layer momentum thickness calculations is also given herein. Due to its simplicity the integral relation method for boundary layer solution still has found practical applications in design and research departments nowadays....

By applying the trap model to the DPM boundary condition type of a wall, the trajectory calculations areterminated after the collision, and the fate of the particle is counted as trapped. Furthermore, theentire mass is converted to the vapor phasein a droplet evaporation simulation. Check the ...
For the pebble bed design, modifying the geometry of bed through adjusting the base cone angle [101] and bottom shape [88] has been verified to be important. Introducing well-designed wall structures is also helpful in avoiding near wall pebble caking in large areas [102]. Show moreView ...
Landscaped areameans all the planting areas, turf areas, and water features in a landscape design plan subject to the Maximum Applied Water Allowance and Estimated Applied Water Use calculations. The landscaped area does not include footprints of buildings or structures, sidewalks, driveways, parking ...
The model of the electric double layer is relatively simple, (a uniformly charged plane for the surface, a homogeneous dielectric continuum for the solvent, and a symmetric binary electrolyte), but the calculations do include two important effects: ion size and ion correlations. As mentioned ...
Hence, the mean values of the wall heat flux into the wall must be accurately estimated for optimal design and cooling of the combustion devices. In this work the normalised wall heat flux is analysed and is defined as Φw=|qw|/[ρRSLcpR(Tad−TR)], where qw=−λw∂T^/∂y|w...
Finally, it is important to emphasize that for the WMLES calculations, the non-dimensional time-step size\Delta t=\Delta t^{\star }{\mathscr{U}}_{\infty }/c(where the superscripts^{\star }denote dimensional quantities) is larger due to the coarse grid resolution near the wall, and appr...
The boundary conditions for solving the aforementioned fundamental equations must consider two types of boundary conditions: (1) thermofluid dynamic boundary conditions, such as a zero velocity on wall surfaces, constant velocity gradient, constant temperature, constant heat flux, and free in- and out...
We lose, however, the mesh formed from pixels, which could be directly used in calculations; cf. Subsection 24.3. If the equation has constant coefficients and if the finite element method is used to solve it, then it is advantageous to have Ωlow and Ωupp starshaped, where Ωupp = α...
