A parametric water-cooling sleeve for a Formula SAE EV motor, built in nTop. A walled gyroid lattice fills the coolant annulus around the stator. The notebook runs a conjugate heat transfer (CHT) analysis to check pressure drop and stator bore temperature. Coolant streamlines through the gyroid jacket, colored by temperature

Installation

Download fsae-cooling-sleeve-gyroid-cht.ntop from the community site, or clone this repo:

git clone https://github.com/nTopology/Utilities-community.git

The package lives at packages/matthewmuellernTop/fsae-cooling-sleeve-gyroid-cht/. The notebook has no external file dependencies.

Usage

Open fsae-cooling-sleeve-gyroid-cht.ntop in nTop 6.1 or later. It was prepared with nTop 6.1.2.
Save a working copy.
Set the motor and coolant inputs: Bore Radius, Active Length, Heat Load, Coolant Flow Rate and Coolant Inlet Temp.
Shape the jacket: Channel Depth, Gyroid Cell Size, wall thicknesses, Plenum Height and port size.
Set Cell Size (the LBM grid), then run Gyroid CHT Analysis. Use 2 mm for DoE screening and 1 mm for final checks.

Defaults

Input	Default basis
Bore Radius / Active Length	Typical FSAE EV inboard PMSM: 120 mm stator, 150 mm stack
Heat Load	About 1.5 kW continuous, for an approximately 80 kW motor, applied as uniform flux on the stator bore
Coolant Flow Rate	8 L/min water (typical FSAE pump)
Coolant Inlet Temp	40 °C radiator-out
Port Radius	Ø12 mm ports (typical -8 AN / 1/2” fitting)
Gyroid Cell Size	43 mm, which gives 10 cells around the mid-channel circumference
Channel Depth	16 mm (8 LBM cells across at 2 mm)

The gyroid sheet thickness is tied to 1.5 × the LBM cell size so that the sheet always resolves. The sleeve material is 6061 aluminum. The coolant is a custom water material with thermal properties, because CHT needs k and cp on the fluid.

Outputs

Output	Notes
Cooling Sleeve	Solid 6061 sleeve: blank minus coolant volume
Coolant Body	Fluid volume: annular jacket minus lattice, plus ports
Pressure Drop	Inlet minus outlet pressure
Bore Temperature	Time-averaged stator bore temperature (lower is better)
Coolant Outlet Temperature	Average temperature at the outlet face
DoE Outputs	`[Pressure Drop (Pa), Bore Temperature (K), Coolant Outlet Temperature (K)]` for nTop Automate

Notes

This copy was saved without analysis results, so run Gyroid CHT Analysis yourself to get the pressure and temperature outputs. The notebook is byte-identical to the shared source and was not re-evaluated in nTop for this submission. Treat the results as exploratory screening unless you run the analysis at the finer cell size.
