Of today's batch, this is the one that actually shows a real engineering workflow rather than a hashtag-laden teaser or a marketing reel. Parametric CFD is how modern turbomachinery design gets done — instead of running a single simulation and squinting at the result, engineers sweep across geometric variables (blade angle, impeller diameter, tip clearance, volute shape) and let the solver map out the performance landscape.

The video promises to walk through that loop applied to a pump: define the design parameters, run the batch of CFD cases, then extract head, efficiency, and power curves to find the sweet spot. That's genuinely useful because the gap between "I can run one Fluent case" and "I can use CFD to make a design decision" is exactly this kind of parametric scripting — and it's rarely taught well in coursework.

CFD Support are the folks behind the OpenFOAM-based TCFD toolkit, so expect a vendor flavor, but their content tends to be technically substantive rather than salesy. Worth watching if you're learning turbomachinery design, evaluating CFD workflows, or trying to understand why a pump's best-efficiency point sits where it does.

Note: several of today's candidates were AI-narrated explainers or thinly-described teasers; this was the clearest substantive pick.
