The solar updraft tower (SUT) is a renewable energy power plant design concept for generating electricity by utilizing convective air flow due to low temperature heat absorption from incoming solar radiation. A parametric study on the performance power output of the SUT at various canopy angles and different insolation levels were carried out to in...

... contour maps of SUT plant at 1000 Wm -2 at 5º canopy angle. Figure 4a, 4b and 4c represents contour maps of variation in velocity profile at 5º canopy angle with respect to varying insolation at 600Wm -2 , 800Wm -2 and 1000Wm -2 while table 6 displays variations in velocity with respect to variation in height of the tower at 5 • canopy angle at different insolation levels of 600 Wm -2 , 800 Wm -2 and 1000 Wm -2 . From figure 4a, a maximum velocity at the center of the tower can be observed that at 600 Wm -2 and 800 Wm -2 insolation levels, indicating suitability of turbine placement for attaining maximum efficiency whereas at 1000 Wm -2 , maximum velocity at the inlet periphery of the collector can be clearly noticed from figure 4c, indicating desirable placement of turbine to extract maximum efficiency with an option to place more than one turbine. ...

... The simulation software program Fluent is widely employed in diverse fields, e.g., aerospace, biology, and energy [18,19], as it offers a variety of grid types (including structural and non-structural), which can be applied before executing the simulation; physical models, such as laminar flow, turbulence, and transmission models; and different types of boundary conditions, e.g., for the inlet/outlet and wall. When executing the numerical simulation, the user can monitor the change in each physical quantity, e.g., speed, temperature, or pressure, in real time while the software performs the calculation according to a set of predefined constraints. ...
The splitter is an important component of water-based cooling systems used to extract heat from computer boards. In the present study, the flow characteristics of a 16-splitter structure were numerically simulated and compared with experimental results to verify the reliability of the numerical simulation method. Accordingly, the concept of splitter structural coefficients was proposed. Based on the results of this study, we recommend a selection range of 5 < k < 6 for the structure factor k of the splitter; after optimization, the maximum deviation of the splitter outlet flow was reduced from the original value of 100% to 8.3%.
