Simulation of moving bodies can be performed directly in FlowVision through either a kinematics or dynamics approach. Any arbitrary shaped object can be defined as a moving body with 6-DOF motions determined by user-defined velocities, user-defined forces and/or fluid-induced forces.
FSI (Fluid Structure Interaction)
As a result of SGGR mesh generation; a natural link is automatically formed with FE (finite element) mesh and FlowVision simulation domain allowing strongly coupled FSI (fluid-structure interactions). Full integration between ABAQUS CSE (Computational Simulation Engine) and FlowVision MPM (Multi Physics Manager) provides co-simulation mechanisms addressing most complex FSI simulations. Without any need for a 3rd party component (such as MPCCI), FlowVision MPM drives the process by controlling the data transfer, by starting/restarting both solvers and providing feedback on the simulation progress.
Unique Clearance (Gap) Model
Thin clearances are often present in flow domains and resolving them with traditional meshing significantly augments computational costs. Furthermore, in many cases, mesh generators are incapable of handling these areas. FlowVision’s unique Gap Model applies a sub-grid model in small clearances which allows calculation of flow properties on regular mesh. FlowVision Gap Model is capable of accurately simulating flows in very thin clearances down to length-to-scale ratios of 10^-6 and dimensions down to 10^-6 meters.
Conjugate Heat & Mass Transfer
With flexible multi-region modeling in FlowVision, different sub-regions containing different phases are easily specified. Once fluid and solid sub-regions are defined, conjugate heat transfer between phases is accurately modeled. In addition, more than one substance can be defined in any phase which allows mass transfer calculations including mixing, combustion and any user defined chemical reactions.
FlowVision EHD solver is used for calculation of a variety of phenomena such as:
Stationary Electric Fields
Joule (ohmic) Heating
Motion of Electrically Charged Bodies in Electric Field
Simulating an EHD problem in FlowVision; dependence of electrical conductivity end dielectric permittivity on concentration of agents, temperature, etc. can be observed or distribution of electric potential and electric field strength can be visualized in computational volume.
