The cyclical input and extn. of heat causes the material to expand and contract. The system operates at a preset pressure. The circuit is connected to a turbine operated by the expansion of the medium. The circuit is so designed that a continuous operation is achieved. The operating pressure...
It’s not exactly the same model the military uses, but this simple hovercraft is a lot easier to build. An old CD and a balloon help demonstrate air pressure and friction in this fun 4th grade science experiment. The STEM Laboratory 34. Create a smartphone projector Difficulty: Medium / M...
Students will enjoy building rockets from straws while experimenting with variables like fin size and weight distribution. This simple engineering project helps students understand concepts like force and motion, center of gravity, etc. Learn more:Rocket STEM Challenge @vivifystem via Instagram 30. Desi...
Mass and momentum equations were solved using the finite volume technique to simulate the two-phase simulation. The transport equation was discretized by the second-order upwind method. The pressure based segregated algorithm SIMPLE was used for transient calculation and body force due to gravity was...
When the hydrogen content was high, hydrogen concentration and hydrogen pressure at the grain boundary were relatively high, resulting in the instantaneous cracking along the grain boundary and hydrogen-induced bubbles. HIC sensitivity increased in the following order: fine granular Materials 2021, 14,...

The results show that the average microstrains of samples with the curvature of 1/4m1, 3/4m1, and 5/4m1impacted by ultra-high pressure water jet are 707, 952 and 1053, respectively, and the strain amplitudes are 300700, 300–600 and 300–560 respectively. The force exerted on the ...
to the theory presented above, the accelerometer scale factor of lateral designs should have a smoother progression over temperature for two reasons: First, it is independent from the actual pendulum position, and secondly the electrode distance is not sensitive to changes of the outside pressure. ...
