How Can I Build an Efficient Stirling Heat Pump?
Did you know that heat pumps are also called Stirling engines? These systems can operate on incredibly low temperature differences — some only need human body heat to work!

Using the Boussinesq Approximation for Natural Convection
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.

Can We Hear the Shape of a Drum?
Over half a century ago, Mark Kac gave an interesting lecture on a question that he had heard from Professor Bochner ten years earlier: “Can one hear the shape of a drum?”

Simulating the Insertion of a Snap Hook
Snap hooks, a type of fastener that involves the insertion of a hook into a slot, are found in the automotive industry. Simulation can be used to analyze their insertion and removal.

Instability in Portable Washing Machines
A varied distribution of clothing can cause walking instability in both traditional and portable washing machines. Multibody dynamics analysis can be used to avoid this effect in machine designs.

Improving the Operational Lifetime of a Reciprocating Engine
Many of today’s motor vehicles rely on reciprocating piston engines as their source of power. Multibody dynamics analysis can be used to analyze the operation and performance of these engines.

The Motions and Mechanics of a Truck-Mounted Crane
The Truck Mounted Crane tutorial model analyzes the forces on the cylinders and hinges of a crane during an operating cycle, combining multibody dynamics and structural analyses.

Modeling Room Acoustics with COMSOL Multiphysics
The field of room acoustics aims to study the sound quality of a space in a qualitative way. The Acoustics Module includes features to simulate the acoustics of rooms and other confined spaces.
