Mixture and Wet Steam Multiphase Model Training Course

Description

Mixture and Wet Steam Multiphase Model Training Course

The Mixture Multiphase Model in Fluent is a numerical simulation tool used to model the behavior of multiphase flows. It is based on the Eulerian-Eulerian approach, which considers each phase as a continuous medium and tracks the motion of each phase separately.

The model can be used to simulate a wide range of multiphase flows, including bubbly, dispersed, and stratified flows. It can also be used to simulate the interaction between different phases, such as heat and mass transfer, and chemical reactions. The model is highly accurate and can be used to predict the behavior of complex multiphase flows.

The Wet Steam model in Fluent is a two-phase flow model that accounts for the effects of condensation and evaporation on the flow. It is based on the conservation equations of mass, momentum, and energy for both the vapor and liquid phases. It can be used to simulate a wide range of two-phase flow problems, such as condensation in a steam turbine or evaporation in a heat exchanger.

There are various CFD methods to employ these models. One of the most renowned methods is the Finite volume method implemented in ANSYS Fluent. ANSYS Fluent is a powerful tool that can simulate Mixture and Wet Steam-based multiphase flows. The implemented options and existing capabilities of this software can predict even the slightest alteration of phases when interacting with each other.

Lesson 2: Boat Propeller Cavitation

In this lesson, we will teach you how to simulate the practical problem of cavitation on a boat propeller. The cavitation phenomenon can wear and erode the surface of propellers or pump blades leading to their destruction sooner than the predicted time.

Hence, by simulating this phenomenon, engineers can alter their design to prevent such incidents from happening. In this session, you learn how to apply the cavitation model using the Mixture multiphase model and how to apply correct boundary conditions to employ this model.

Lesson 3: Wet Steam for Condensation inside a Steam Ejector

In this lesson, we present another realistic industrial problem which is the formation of water liquid droplets inside a converging-diverging nozzle. The Wet steam model can be used to predict the formation rate of water droplets as the supersaturated dry vapor passes through the throat of a converging-diverging nozzle.

As the supersaturated dry vapor passes through the neck of the nozzle, a sort of shock is applied to the flow stream, causing the dry vapor to condense into liquid droplets. This phenomenon is studied extensively for many applications such as power plants, biomedical, and food industries.
