A look at Solar Radiation in SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

The holidays are in full swing, and with them comes shorter days and the dreaded cold of Winter. This time of year, there is nothing I look forward to more than the return of summer sunshine. Luckily SOLIDWORKS Flow Simulation can help cure the winter blues with its advanced solar radiation capabilities. Let’s take a look. Many people are aware that SOLIDWORKS Flow Simulation is an industry leader in CFD (Computational Fluid Dynamics) heat transfer, and it includes robust radiation […]

SOLIDWORKS Flow Simulation: A Tesla Cybertruck Case Study

EmailFacebookLinkedInTwitterShare

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

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). […]

I am always looking for new and exciting ways to combine our great products to make something even better. In my line of work, one of the best combos is the unique marriage between the powerful FEA capabilities of SOLIDWORKS Simulation and the great CFD performance of SOLIDWORKS Flow Simulation. Together they allow a one-way CFD to FEA fluid-solid-interaction (or FSI). But does it stop there? I found a great example the other day that sparked my interest; the duckbill […]

SOLIDWORKS 2020 What’s New – SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

Every Year SOLIDWORKS releases updates and enhancements to the Flow Simulation Software. 2020 is no different bringing three new functionality additions. Altitude The general settings are enhanced by the addition of Atmospheric Pressure, and Temperature being linked to Altitude. Using a What If Scenario will allow the user to depict a flight path with increasing or decreasing altitude. Fan Derating Located in the Fan property manager the Fan Derating factor produces more realistic results based on fans typically not running […]

SOLIDWORKS Flow Simulation: Calculation of Hydrostatic Pressure

EmailFacebookLinkedInTwitterShare

If you are an experienced SOLIDWORKS Flow Simulation user, chances are you’ve turned on the “Gravity” setting to account for buoyancy effects that exist when a fluid’s density changes with temperature. This is a very commonly used feature of the program. Buoyancy is an amazing physics principle that allowed the Montgolfier brothers to make the historic first “lighter than air” flight in Paris in 1783. One thing you may not be aware of is that when the gravity feature is […]

SOLIDWORKS Flow Simulation: HVAC Module Part 1 – Tracer Study

Predicting the way that fluids behave and mix inside a closed space can be a difficult undertaking. Every day we are at the mercy of the HVAC systems that not only expel or filter harmful air but maintain comfortable temperatures. There is a lot to consider in these types of problems, and without some sort of assistance, it can be little more than guesswork. SOLIDWORKS Flow Simulation does a great job of calculating the types of parameters we are used […]

SOLIDWORKS Flow Simulation: Radiation! A Follow-up Blog

EmailFacebookLinkedInTwitterShare

A few weeks ago, I published a blog that discusses the basics of radiation in SOLIDWORKS Flow Simulation. The link to the blog can be found here. In that blog, we used a very simple example of a one square meter plate to demonstrate the accuracy of SOLIDWORKS Flow Simulation compared to well-established hand calculations. In short, a 1 square meter plate with an emissivity of 1 at 300 Kelvin should have a radiative heat transfer rate of 459.29 [W], […]

SOLIDWORKS Flow Simulation: Remote Solver Setup

Think about the last time you needed to solve a very large SOLIDWORKS Flow Simulation project.  Did your workstation have enough horsepower to solve the project in a reasonable amount of time?  If not, did you have access to a high-end workstation elsewhere in your office that you could have connected to?  If the answers to those questions are ‘no’ and ‘yes’, respectively, then you could have taken advantage of SOLIDWORKS Flow Simulation’s Remote Solver capability.  Utilizing the Remote Solver […]

Hot Air Goes Up, Right? Confirmed With SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

Warm air rises, and Cold air descends. This is a simple concept that we learned early on in life. We can feel it if we place our hand above a hot stove, or notice our basement is always the coldest part of the house. But why does this happen, and what does this have to do with SOLIDWORKS Flow Simulation? Warm air rises and cold air sinks due to gravity. Yes, gravity the invisible force that holds all of us […]
