Exploring the Venturi Effect

October 19, 2015

The Venturi effect: As a fluid flows through a constructed area of a pipe, its velocity increases and its static pressure decreases. Learn more about this effect and its application areas.

How to Calculate Mass Conservation and Energy Balance

October 14, 2015

Ever wonder how to compute the mass conservation of a fluid flow simulation, or the energy balance of a conjugate heat transfer simulation? If so, keep reading >>

Evolving into a Better Design: Humans and Technology as One

September 15, 2015

Read about how the concept of constructal law applies to the joint evolution of humans and technology in this blog post about a keynote talk from the Conference of the Academia Europaea 2015.

Simulating Viscous Heating in a Fluid Damper

September 9, 2015

Fluid dampers are able to dissipate mechanical energy into heat through a process called viscous heating. You can simulate this process to optimize your fluid damper designs.

Intro to Optimizing Mixer Design by Creating an App

July 6, 2015

By building a simulation app to study mixer designs, you can easily test the influence that the vessel, impeller, and operational conditions have on the design’s mixing efficiency.

How Do I Compute Lift and Drag?

June 16, 2015

Analyzing lift and drag is an important task in many industries, such as automotive and aeronautics. Learn some different ways to compute lift and drag in COMSOL Multiphysics®.

Describing the Behavior of a Thermal Mass Flow Sensor

April 27, 2015

Researchers from the University of Cambridge analyzed the dynamics of a thermal flow sensor, a component of a flowmeter, with a 3D model. Get the full story >>

Using the Boussinesq Approximation for Natural Convection

April 7, 2015

Today, we compare the Boussinesq approximation to the full Navier-Stokes equations for a natural convection problem. We also show you how to implement the Boussinesq approximation in COMSOL Multiphysics software and discuss potential benefits of doing so.
