Design for Altitude with SOLIDWORKS Flow Simulation 2020 As an engineer and a space enthusiast, I am deeply excited about the recent SpaceX Dragon launch. The Dragon launch was the first American based launch of NASA astronauts since 2011, and it will hopefully push NASA to consider more American based space launches for years to come! With that being said, the process to launch the Dragon spacecraft required multiple design iterations and validation to ensure a safe and effective launch. […]

In Part 1 of this two-part blog I highlighted some of the main characteristics of SmartCells, the unique technology found ‘under the hood’ of SOLDWORKS Flow Simulation that provides for speed, accuracy and ease-of-use of the software. To recap, the five most important features are: SmartCells are Cartesian based meshes that are typically an order of magnitude smaller in size (i.e. cell count) than traditional CFD meshes while still providing the same level of resolution and accuracy SmartCells handle complex […]

Particle Separation using SOLIDWORKS Flow Simulation

Particle separators are important devices used to clean industrial process air. One such device that uses inertial and gravitational forces as the separation mechanism is shown in simplified form below. The top view shows that the inlet introduces the flow in a direction that is tangent to the separator wall. In principle, as the flow is introduced, the inertia of the entrained particles makes them collect near the separator walls. Clean air collects in a vortex near the center of […]

The field of Computation Fluid Dynamics (CFD) is a sophisticated engineering discipline based on the Reynolds Averaged Navier-Stokes (RANS) equations that govern fluid flow, heat and mass transfer. CFD has a reputation for being extremely complicated and has typically been the domain of specialists, physicists and academics, using super computers. Typically, the quality of CFD results is greatly affected by the quality of the mesh and the attentiveness of the user to the pre-processing stage. Consequently, traditional CFD software codes […]

In my previous blog, I showed an application of the free surface feature in SOLIDWORKS Flow Simulation. For a 2D section of a spillway and flow over a weir, I showed how this feature can accurately predict the hydraulic jump. Well, 2D isn’t that exciting, is it? That’s why we love to use SOLIDWORKS in the first place! So I generated a 3D simulation and found impressive looking results while learning some new things along the way. Here’s the model […]

SOLIDWORKS Flow Simulation: A Tesla Cybertruck Case Study (Part 2)

EmailFacebookLinkedInTwitterShare

In part 1 of this Blog article I investigated the drag characteristics of the Tesla Cybertruck and explored how symmetry boundary conditions can be used to speed up a flow analysis project in SOLIDWORKS Flow Simulation. In part 2, I am going to demonstrate some of the nuances for correctly setting up a “Virtual Wind Tunnel” in SOLIDWORKS Flow Simulation. Before the widespread adoption of Computational Fluid Dynamics (CFD), engineers who sought to explore the aerodynamics of different vehicle shapes […]

SOLIDWORKS Flow Simulation: A Tesla Cybertruck Case Study

When Tesla launched their Cybertruck pickup model in November, I was intrigued by its unique shape. Given the very angular, wedge-like styling, the first thought that came to mind was that I could have designed the exterior shape in SOLIDWORKS in 5 minutes with a few extrudes, cuts and draft features. I have no doubt that I could have saved Tesla millions of dollars spent on their exterior stylists and designers! I also pondered whether this shape performed well aerodynamically […]

SOLIDWORKS Flow Simulation: Hydrology Applications

EmailFacebookLinkedInTwitterShare

With the addition of the free surface capability, SOLIDWORKS Flow Simulation can now perform simulations of more real-world applications. One commonly encountered Civil Engineering application in open-channel flow design is an energy-dissipation phenomenon called hydraulic jump, which occurs when a fast-moving, shallow flow encounters a relatively slow-moving, deep flow field. Fluid Mechanics texts classify open-channel flow using the dimensionless Froude number (Fr), which is a function of the fluid velocity (V) and depth (y) (ref. F. M White, Fluid Mechanics). […]
