Rotating mesh CFD analysis

Rotating mesh CFD analysis In many engineering applications it is important to simulate the flow around a rotating component. Typical applications are the simulation of flow around propellers, wind turbines or mixing vessels.   This tutorial shows the application of the rotating mesh CFD analysis to the simulation of a mixing vessel and the impact the […]

Multiple Reference Frame (MRF) CFD analysis

Rotating mesh CFD analysis using the MRF approach We have seen in the Mixing Vessel tutorial how to setup a physical mesh rotation of the impeller in the mixing vessel. While this is the best approach to simulate rotating bodies,  it is also computationally expensive. If we are more interested in the effect of the […]

Porous media in a pipe

Porous media to simulate a filter placed inside a pipe In many engineering applications porous media like radiators, filters or vents in the flow will create a blockage or a pressure drop on the flow itself. While i is possible to model them explicitly meshing every detail of the element, this would require an extremely […]

2D CFD analysis of internal flows

2D CFD analysis SimWorks cannot perform pure 2D CFD analysis, however it is possible to run a quasi-2D simulation using an extruded 3D geometry and a specific set of boundary conditions on the outer domain. Moreover, it is possible to use an outer domain smaller than the geometry itself to define an internal flow analysis, […]

SimWorks Advanced Introduction

Introduction to SimWorks (advanced features) This tutorial introduced some new functionalities of SimWorks and expands what has been already described in the SimWorks introduction tutorial. If you have not done it yet, we strongly recommend reading the introduction tutorial before proceeding futher. Create a new simulation Create a single simulation within a Geometry In the […]

Truck side skirts simulation

truck side skirts cfd simulation

Truck side skirts simulation The truck skirts simulation tutorial looks at the effect of adding side skirts to a typical semi-trailer truck. The simulation is carried using our Computational Fluid Dynamics software SimWorks. Before continuing with this tutorial, we recommend to read and complete at least one base SimWorks advanced tutorial to familiarise with the […]

Fume extraction simulation

fume extraction simulation using cfd software simworks manager

Fume extraction simulation tutorial Fume extraction is an important topic for the environmental health in a city. A Computational Fluid Dynamics simulation can effectively calculate the effectiveness of the solution chosen and predict in a reliable way the fume pattern and whether it will hit other buildings or affect pedestrians. Once this phase is completed […]

Emergency room simulation

emergency room simulation

Emergency room simulation An emergency room is designed to house several patients at the same time. It is important to be able to assess and minimise the dispersion of airborne pathogens inside the emergency room to avoid the spreading of diseases. A Computational Fluid Dynamics (CFD) simulation is carried out to simulate how the pathogen […]

Negative and positive pressure rooms CFD simulation

negative pressure room CFD simulation

Negative and positive pressure room CFD simulation A CFD analysis of the interaction between a positive pressure room and a negative pressure room on a typical hospital floor is presented. A negative pressure room is designed to prevent a contaminant from spreading to other parts of the building by having only flow coming into the […]

Negative pressure room simulation

negative pressure room CFD simulation

Negative pressure room CFD simulation In this tutorial, a Computational Fluid Dynamics (CFD) simulation of a negative pressure room is described. The pressure inside the room is maintained lower than that of the nearby rooms to prevent air, and potential contaminants, to escape and spread in other spaces. With a CFD simulation is possible to […]
