Fluid dynamics scaling laws
WebThe model proposes that there is no universal scaling law for the Nusselt number but that is dependent on the region of Rayleigh/Prandtl number space in which the experiment takes place (see [ 28] Figure 2 ). In the new annulus the heat source and sink are displaced both vertically and horizontally from each other. WebAn integral reactor design methodology was developed to address the optimal design of photocatalytic wall reactors to be used in air pollution control. For a target pollutant to be eliminated from an air stream, the proposed methodology is initiated with a mechanistic derived reaction rate. The determination of intrinsic kinetic parameters is associated with …

WebFeb 22, 2024 · Although the scaling laws are proposed only for the ideal superhydrophobic surface, they are tested valid for θ over 73° owing to the ignorable zero-velocity spreading effect. Furthermore, combining the two scaling laws leads to an impact number, $W {e^ {3/10}}O {h^ {1/3}} = 2.1$. WebThe working fluid is nitrogen, and its viscosity was calculated by using the Keyes law .
