CASE STUDIES

Work you can check.

Three studies we ran ourselves: transonic pressure against wind-tunnel data, a free-surface hull against towing-tank data, and a data-center layout taken from geometry to a defensible recommendation. Every page shows both the result and its claim boundary.

VALIDATIONMarine free-surface CFD

Sinkage within 1.03 mm. Resistance we won't call validated.

Start here for how we tell a bug from a physics result.

The 3 m Wigley hull from Fr 0.177 to 0.408, against the 1983 towing-tank measurements. Every sinkage result landed within 1.03 mm — but only after a constant +6.6 mm offset gave away a datum bug that no amount of physics tuning would have fixed. Total resistance is verified to ±2.10% on a converged grid family, and stops there: no measured Ct for this hull is in our hands.

DESIGN STUDYData-center thermal management

How much cooling capacity does your layout cost you?

Start here for what an engagement looks like.

An independent study we ran on our own bench: four ways of arranging 42 dry coolers around a 44 MW-class data hall. The dense baseline quietly lost about 12% of its cooling capacity to its own exhaust; a better layout cut that penalty to about 5%.

VALIDATIONTransonic external aerodynamics

The λ-shock, where the wind tunnel puts it.

Start here for what our numbers are worth against measurement.

The ONERA M6 wing at Mach 0.8395 against AGARD AR-138. 270 of 271 pressure taps, and the double-shock structure captured and merging where the experiment brackets it. Lift sits 1.1% from the midpoint of a NASA multi-code band — a code-to-code check, not validation; there is no measured lift or drag for the M6.
