You will see how Group Technology st...

This episode dives into one of the most misdiagnosed failures in rotating equipment: the shaft that quietly destroys seals, bearings, and uptime while everyone blames the wrong part.

This episode tears into the uncomfortable truth behind thermal modeling: the spreadsheet was right, the hardware still overheated. We break down why clean heat-transfer equations fall apart in the field. Assumptions like uniform material properties, ideal contact surfaces, steady-state flow, and perfectly known boundary conditions rarely survive manufacturing tolerances, oxidation, vibration, and...

This episode maps the hard performance limits of turbomachinery, where the math stops being polite and the flow starts doing whatever it wants.
