What Factors Influence Pressure Drag at the Nanoscale?
Several factors influence pressure drag at the nanoscale, including:
1. Shape and Size: The shape and size of nanoparticles have a profound effect on pressure drag. For example, spherical nanoparticles typically experience less drag compared to irregularly shaped particles. 2. Surface Roughness: The roughness of the nanoparticle surface can alter the pressure distribution around the particle, thereby affecting the drag. 3. Fluid Properties: The viscosity and density of the fluid in which the nanoparticles are suspended also play a crucial role in determining the magnitude of pressure drag.
