WebSep 8, 2024 · MAPUA UNIVERSITY School of Civil, Environmental and Geological Engineering A free body diagram of the sphere after it has acquired constantvelocity or terminal velocity is shown on the sketch where W is the weight of the sphere. F b is the buoyant force and F d is the deformation drag. A falling-sphere viscometer is a device used to measure the viscosity of a fluid by measuring the time required for a spherical ball to fall a certain distance under gravity through a tube filled with the fluid whose viscosity is to be determined. When the sphere is dropped, the sphere experiences three forces: … See more In this simulation example, you will learn: • How to simulate the flow over a sphere in Ansys Fluent and compute the resulting drag forces • How to … See more Download the mesh file needed for setting up the simulation and the associated Case and Data files here.
