Modelling of direct acting relief valve using CFD-FSI simu

100%

Domagała M.

This paper presents an attempt of using new capabilities of CFD tools in field of fluid-structure interaction simulation, which is called “immersed solids”. This techniques treats solids as objects immersed into fluid domain which moves along with the fluid. This paper presents comparison of selected CFD results of traditional approach and “immersed solids” technique on example of direct acting relief valve.

Simulation of cavitation in jet pumps

100%

Domagała M.

This paper presents simulation of cavitation phenomena at jet pumps with use of CFD methods. There was also presented theoretical consideration of cavitation formation and models applied at the CFD codes. On example of liquid-jet liquid pump, which working medium is water was presented simulation of cavitation process which was conducted in Ansys CFX code. This paper also includes some selected results of simulation for fluid flow at the jet pump with consideration of cavitation process.

CFD simulation of transport solid particles by jet pumps

63%

Momeni H. , Domagała M.

This paper presents CFD simulation of solid particle transport by jet pump. Simulation was conducted using Lagrangian-Eulerian CFD approach. There is presented simulation of transport of mixture of water and solid particles with various density by jet pump with annular motive nozzle. The CFD simulations allowed to obtain trajectory for individual particles as well as theirs maximal velocity.
