An Eulerian/Lagrangian approach is used to calculate the physical forces acting on a spherical
bubble. Reynolds average Navier–Stokes (RANS) equations for the Eulerian approach are solved with a
finite volume scheme. The SIMPLE algorithm is utilized for pressure and velocity linkage. To model
convective fluxes, an upwind scheme is used. The Reynolds stress transport model (RSTM) is used to
calculate the turbulent parameters. In the Lagrangian approach, a modified form of the
Reyleigh–Plesset (RP) and Maxey equations are solved with MATLAB programming software for evaluation
of bubble motion and bubble dynamics. The carrying fluid in this study is diesel fuel. Continuous
filter white noise (CFWN) is solved parallel to the Maxey and RP equations to calculate fluctuating
terms of velocity in x and y directions. Six forces exerted on the bubble during its motion are
investigated inside the cavitating flow regime. The cavitating regime can be extremely effective on
bubbl…
