Fans & Mixers

XFlow is used to simulate real rotating fans or alternatively model them using a simplified fan boundary condition.

Agitators and mixers for the chemical industry, water treatment plants or even domestic devices are easily simulated with XFlow. It solves single and two-phase flows for immiscible fluids including surface tension. Scalar transport models are available and can be used to track the fluids mixing evolution.

Design optimization analysis of fans and mixers can also be performed in XFlow thanks to the different integration possibilities available with third party optimization software.

Nozzles & Sprays

Fluid atomization and spray droplets are simulated using the free-surface or multiphase solver in XFlow and tracked dynamically with the adaptive refinement feature of XFlow which dynamically and locally refines the regions where the droplets are splashing.

Such a capability in XFlow now makes some automotive applications possible by CFD such as windshield washer nozzles.


Valves & Pumps

XFlow easily handles moving parts with Enforced and Rigid Body Dynamics behavior which is suitable for Valve applications where it is very important to simulate the valve dynamics. It is also possible to specify a law to model the spring force applied on the valve. XFlow has already demonstrated its accuracy in predicting the pressure drop as a function of the flow inside the valves as well as the vibrations and instabilities of valves.

Centrifugal or displacement pumps are set up and simulated very easily, not only for isolated operational points but also for full cycles or accidental events in which the engineer wants to analyze in detail the transient dynamics of the system.

Thermal Management

The thermal fluid applications can be solved with XFlow thanks to the different thermal solvers available in the code. It allows thermal analysis together with aerodynamic analysis to be performed, which is very important for cooling/heating problems.

The Conjugate Heat Transfer model of XFlow allows the conduction inside solids to be solved and simulates, for example, how a hot external flow affects the internal temperature distribution inside a solid.

For manufacturing applications where electronics components are placed close to heat sources, the radiation contribution is very important. XFlow provides a surface-to-surface radiation model where the emissivity coefficient of each surface can be specified in order to solve the contribution of each surface in the global thermal analysis.


Multiphase Flow

State-of the-art multiphase solvers are implemented in XFlow in order to enable the user to solve the interaction between two fluids at different scales with different density and viscosity ratios, for inertial or viscous dominant applications.

These multiphase solvers give the possibility to simulate a wide range of manufacturing applications such as bubbles creation, fluids mixing, lubrication and fluid atomization.

Non-Newtonian Flow

Highly viscous non-Newtonian fluids (e.g. melted plastic, molding, chemical blends, toothpaste) are common in many industrial applications. The complex rheological properties of these fluids can be introduced in XFlow by using the predefined viscosity models available (Newtonian, Sutherland, Cross, Herschel-Bulkley, Power Law, Carreau) or user-defined functions.
