Imagine a world where air is the coolest roller coaster you've ever seen. No rickety tracks, no screaming kids (except maybe you, as a scientist), just pure, unadulterated airflow. That's basically what we're about to build in SimScale, folks – a virtual wind tunnel for a pipe!
The annual Materials Mania competition was upon them again. Dr. Patel, a passionate engineering professor, paced excitedly in front of her two brightest students, Maya and Alex. This year, the challenge was a beam brawl - two identical beams, one steel and one aluminum, would go head-to-head to see which could hold the most weight before buckling.
Have you ever wondered how much weight a bridge can hold before it groans in protest? Or how tall a skyscraper can be before it needs super-strong beams to keep it from toppling? The answer lies in understanding beam strength, and that's exactly what we'll be exploring in this SimScale tutorial! Buckle up and get ready to analyze beams like a pro!
In today's post, I would like to present you a comparative analysis of the aerodynamics of gas flow around medieval bullets and bullets that we deal with today. We will try to answer the question why the shape of the bullet has changed so significantly.

As I announced in the previous post, today there will be a duel for the same obstacles, while the player will be water. The main difference between these two liquids (water, oil) is the density and viscosity which has a fundamental influence on the formation of the forced stream that encounters obstacles.

Today I would like to present you a duel of two obstacles that will be overcome by invincible oil (properties and types are given below). We will check which obstacle is more effective in fighting with this fluid. Two analyzes (two obstacles) were performed as Incompressible Flow in SimScale.

The next step in modeling CHT analyzes is taking into account the radiation phenomenon. In the SimScale software, we add the radiation model when selecting the type of analysis and the type of turbulence we want to apply to our geometry.

In today's tutorial, I would like to present the supersonic gas flow analysis with the suction phenomenon from the second inlet defined by pressure. For this type of analysis in SimScale we choose Compressible Flow Analysis which is used to model analyzes for gas velocities above 0.3 Mach Number.

Another tutorial I would like to introduce to you is the CHT analysis. It is one of the most commonly used types of simulation. In SimScale, you can go through all the phases of Conjugate Heat Transfer (CHT) modeling in a few simple steps.

SimScale, as I mentioned in the previous post, is a revolutionary platform where, using only a browser, we are able to go through all stages of CFD modeling. We don't need costly working machines or any software investment. All it takes is a bit of willingness which, through the very friendly and intuitive SImScale interface, will lead us towards solving our problems related to fluid mechanics.
In today's post, which is divided into two parts, I would like to show you a single flow tutorial based on compressible gas. The configuration of two inlets and one outlet is to show you the interesting phenomenon of quasi-pump in inlet 2 caused by the main gas stream in inlet 1. More details below.
