Inspiring Kids About STEM This Holiday Season

black friday STEM gift ideasThis week marks traditionally the biggest eating and shopping days of the year in the U.S. On Thursday, Thanksgiving Day, many of us will gorge ourselves with turkey and stuffing or lentil loaf and all the yummy sides in my case. Then, on Friday, Black Friday, many people will hit the malls and shopping centers in hopes of scoring some excellent deals on their Christmas shopping.

I will be cozy at home. I strongly dislike crowds and shopping. But, just like many, I have my sons and nieces and nephews that I like to give presents too. And, just like many of us, I want to buy something these kids can learn from and be inspired by. Inspired for what? A career in STEM of course. Fortunately for me and the little rug-rats in my life, it is easier than ever to buy STEM-inspiring toys for kids of all ages with the help of online shopping and excellent guides to point parents looking to inspire kids in the right direction.

Speed Design and Production of Extrusion Dies Using CFD

extrusion diesExtrusion is a high-volume manufacturing process in which any of a multitude of polymers are melted, formed into a continuous profile and then cut to length. The process results in a wide variety of low cost, high volume products that show up in every aspect of our lives from drinking straws, medical tubing and piping to weather stripping, deck railings and window frames.  But because they are so common, profit margins can be slim and manufacturers are looking at every angle to find ways to lower costs and increase their margins.

Modelling Compressible Flows in ANSYS AIM

In all real life flows, the properties of a fluid material vary with pressure and temperature. The degrees of these variations depend on both the fluid itself and the flow regime. Some engineering simulations can assume constant material properties, but compressible effects are considered significant above a Mach number of around 0.3. Hence, in order to model applications such as external gas flows, nozzles and exhaust systems, material modelling techniques are required that can capture these material property variations.

In ANSYS AIM 16.2, we have incorporated the ideal gas model to determine the fluid density using the ideal gas equation of state. AIM also provides users a way to prescribe temperature dependent variations of other material properties (Specific Heat, Dynamic Viscosity and Thermal Conductivity), either by using an algebraic expression or by defining a table of values.

Advancing Solid Rocket Propulsion System Design

concordeIt has now been over a decade since commercial travelers were able to experience supersonic flight on the Concorde aircraft. News items will periodically surface about the possibility of travel across the Atlantic in an hour or less, but these are usually media hype based on a recently filed patent or publication. The reality is that we are still many years away from a commercial aircraft that can match the speed of Concorde. And, this is a plane that first flew close to 50 years ago. Who knows how far away we are from the transportation technologies we were supposed to have on the recently passed Back to the Future Day, October 21st 2015. Continue reading
