Simulating UHV/CVD and Silicon Growth on a Wafer Substrate
Ultrahigh vacuum chemical vapor deposition (UHV/CVD) is performed at pressures below 10-6 Pa, or about 10-8 torr. In this process, molecular flow is used to achieve gas transport.
Simulating Analog-to-Digital Microdroplet Dispensers for LOCs
University of Bridgeport researchers designed a high-throughput microfluidic droplet dispenser as an analog-to-digital microfluidic converter for use in lab-on-a-chip (LOC) applications.
Describing the Behavior of a Thermal Mass Flow Sensor
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 >>
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.
Studying the Airflow Over a Car Using an Ahmed Body
The Ahmed body is a benchmark model widely used in the automotive industry for validating simulation tools. We discuss simulating airflow over an Ahmed body to optimize automotive aerodynamics.
An Analysis of Syngas Combustion in a Round-Jet Burner
By combining the Reacting Flow interface and the Heat Transfer in Solids interface, we can study the syngas combustion in a round-jet burner. Get details…
Tears of Wine and the Marangoni Effect
Have you ever noticed that when drinking a glass of wine, sometimes “tears” fall down in the inside of the wine glass? This is the Marangoni effect in action! Learn more and see examples…
