The simulations were performed for steady state operation using ANSYS- CFX software, which used a finite volume discretization method to solve the fluid flow equations in the computational domain. For the convective terms, the second-order upwind discretization scheme was used and for the pressure-ve...
In total, 456,945 hexahedral and a few wedge-type cells were used to form the computational mesh, as shown in Figure 6. A maximum skewness of 0.70 with an average value below 0.08 and a minimal orthogonal quality of 0.59 with an average value of 0.98 were achieved. Figure 6. ...
This study developed a user-defined function (UDF) in ANSYS Fluent to solve for MAA [49]. The room mean MAA was 𝜏𝑟 τr¯ used to calculate the AEE of the toilet and is calculated by the following equation [57]: 𝜏𝑟 =∫0∞𝑡⋅𝐶e(𝑡)𝑑𝑡∫0∞𝐶e(𝑡)𝑑...
1. Define the Solid setup in Ansys Simulation (Ansys Workbench). This includes an Fluid-Solid-Interface. 2. Write an Ansys Input File (.inp) of this setup. 3. Define the Fluid setup in Ansys CFX-Pre. A link to the Ansys Input File is required. ...
Full size image As in Fig. 3, the medium and dense grids are drawn with structural grids. The grid aspect ratio is close to 0.97, and the maximum deviation angle of the opposite side is no more than 30°. The number of medium grids is 886,700 and the number of dense grids is 1,...
