SOLIDWORKS Flow Simulation: HVAC Module Part 1 – Tracer Study

EmailFacebookLinkedInTwitterShare

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 […]

Radiation in SOLIDWORKS Flow Simulation

EmailFacebookLinkedInTwitterShare

I have been asked a lot recently about the radiation capabilities in Flow Simulation. No this isn’t the type of radiation depicted in the recent smash hit Chernobyl on HBO. In our case, we are concerned about electromagnetic (EM) radiation. In particular, the capability of EM radiation to transmit heat energy. Of the 3 modes of heat transfer (conduction, convection, and radiation), radiative transfer is perhaps the most overlooked in simulation. I decided to go into a bit more detail […]

Flow Simulation: Computational Domain Editing Part 2 – Periodicity

EmailFacebookLinkedInTwitterShare

In Part 1 of this blog series, I covered the SOLIDWORKS Flow Simulation computational domain symmetry condition setting to reduce the size of the computational fluid dynamics (CFD) problem to be solved. The result is a decreased solution time and required computer memory. This blog will show how another computational domain condition, periodicity, can be used in those situations where you have a pattern of identical components in the flow field. I’ll continue to use the Lockheed F-117 Nighthawk stealth […]

Flow Simulation: Computational Domain Editing Part 1 – Symmetry

EmailFacebookLinkedInTwitterShare

As with any engineering analysis project, efficiency is very important. If you use SOLIDWORKS Simulation for your structural finite element analyses (FEA) studies, you are probably familiar with the symmetry boundary condition, which greatly reduces the size of the problem and the time to solve it. Flow Simulation has a similar capability, and it is just as important to leverage this functionality because the computational fluid dynamics (CFD) method in use with Flow can take a while to solve for […]

SOLIDWORKS Flow Simulation Verification. Verified!

Verification that the software you use is doing what it is supposed to do is nothing new. We just may not know how to access this information. Like my colleague Kurt Kurtin who discussed the SOLIDWORKS Simulation Verification documents in his blog Simulation Verification – How Accurate are My Results, I wanted to make sure you knew where these verification documents are located for SOLIDWORKS Flow Simulation. The Flow Simulation verification documents are a little more hidden than the one […]

SOLIDWORKS Flow Simulation Electronics Cooling Part 3: Heat Pipes

EmailFacebookLinkedInTwitterShare

Welcome to part 3 of the blog covering the added capability the Electronics Cooling Module offers to SOLIDWORKS Flow Simulation. If you have not done so yet, I recommend reading Part 1 and Part 2. In these previous blogs, we talked about Joule heating, improved PCB definitions, Two Resistor Components and more. This final blog in the series is reserved for the Heat Pipe functionality included in the Electronics Cooling Module. Heat pipes are a critical component in any modern […]

SOLIDWORKS Flow Simulation Electronics Cooling Part 2: PCB & Two-resistor Components

EmailFacebookLinkedInTwitterShare

Welcome back to this discussion about the SOLIDWORKS Flow Simulation Electronics Cooling Module. Find a link to Part 1 Here. In part one we discussed Joule heating. Using my neat CATI Printed Circuit board model we were able to simulate the heat generated from electrical power flowing through PCB busses. In that study, we left the heat generated by the IC chip out of the analysis. The purpose of this blog is to take the analysis a bit further. We […]
