The discrete element method is used to simulate the motion and interactions of discrete particles in a dynamic environment such as a ball mill. This method uses contact models for an accurate characterization of the contact forces between the particles during their motion. In this paper, a process...
Influences of the Operating Conditions on the Rotordynamic Forces Acting on a Three-Bladed Inducer Under Forced Whirl Motion. J. Fluids Eng. 2015, 137, 071304–071304-10. [Google Scholar] [CrossRef] Valentini, D.; Pace, G.; Pasini, A.; Torre, L.; Hadavandi, R.; d’Agostino, L. ...
This process is short, and it can be considered to retain the uniform motion vrs, so t = D/vrs. Accordingly, the impact force of a single raindrop Fr is 𝐹𝑟=112𝜌𝑟𝜋2𝐷2𝑣𝑟𝑠2Fr=112ρrπ2D2vrs2 (7) It is assumed that the single rain droplet is A = π D...
That is, in the case of point particle, a 1D curve (the trajectory) mapped into another topologically equivalent 1D curve (but same trajectory) should not change our understanding and the description of the motion of a point particle. Physically, one talks about the covariance principle when ...
