Simulating an Engine Governor, the Spring Loaded Centrifugal Governor
We’ve probably all seen centrifugal force in action in one way or another, whether it be riding on a merry-go-round as a child, spinning a bucket of water upside and observing as the contents hug the insides of the bucket, or watching mud spinning off of a turning tire. In addition to making dizzying carnival rides, this force can be used in the design of many mechanical applications, where it is harnessed to control a variety of effects. One such […]
CFD Applied to Two-Phase Flow, an Italian Dressing Simulation
The fact that oil and water don’t mix is something that you are probably all familiar with. At one point or another, you’ve most likely noticed what happens when you shake a bottle of say, Italian salad dressing, and the liquids mix momentarily, only to become separated again within seconds as oil bubbles rise to the surface. Creating a simulation describing how these two immiscible fluids interact is a great way to introduce computational fluid dynamics (CFD) applied to two-phase […]
A Recipe for Induction Stove Design Using Multiphysics Simulation
When I was little, I used to love spending the night at my grandparents’ house, where I was allowed to watch TV, stay up late, and in the morning, help my grandmother make pancakes. The hardest part was always waiting for her old, slow electric burner to heat up — to my six-year-old self, it seemed to take hours for the burner to become hot enough after we’d finished mixing the batter. Luckily for me, and for other impatient chefs […]
Water Purification Using Ozone
Water purification is the process by which chemicals, contaminants, and sediments are removed from dirty water to make it clean, and there are many processes through which this can be done. What you might not know, is that ozone molecules can be used as a means of disinfection in the purification process. “Ozonation” has been used to purify water, kill germs and bacteria in food, and even get rid of bad smells. Not only does ozonation provide clean water without […]
