Blasting a jet engine into a fan duct, I wonder what will happen with the supersonic flow.

Main Duct_300_Before Change

H2D-R with connected to Main Duct size of 300mm with main duct open on the side.

Updated version of the first duct design, for dual 5015 blower fans

Mini Kossel hotend mount/fan duct for 2 4020 blower fans

Flow simulation of custom fan duct modified for Volcano

Part cooling fan duct for Anycubic i3 Mega S with E3Dv6 hot end. Updated exit geometry to alter the exhaust angle upward slightly in order to impinge on the bottom of the nozzle ncompared to Rev D v6.

This is a fan duct air flow test for E3D V6 hotend conversion for JGAurora A5, with small 30 mm fans to reduce weight and need to use voltage convertors.

Adjusting exhaust angle slightly upward - too low on v6

Adjusted internal fencing, adjusted nozzle exit angle upwards

More downward exhaust angle, more acute exit angle. v5 was still impinging on the nozzle.

Exhaust angle is just a bit high on the nozzle, adjusted to lower slightly. Added vertical fence in exhaust path (to improve flow routing and printability on the forward nozzle only - to check resultant flow.

Completely new duct exhaust design compared to previous revisions. Exit path is flat except for last bit of exhaust, which is angled downwards.

Adjusted exhaust entry to bottom of part. Exhaust angle deflected lower again over Rev F v3.

Fan duct for part cooling. Adjustment of exhaust exit angle slightly downwards over Rev F.

Increased exhaust angle downwards as v4 was impinging on nozzle

Part cooling fan duct for Anycubic i3 Mega S with E3Dv6 hot end - revision 3. Updated exit geometry to alter angle upward slightly on the rear exhaust and also a change to improve the directional output in the X-Y plane compared to Rev D v4.

Part cooling fan duct for Anycubic i3 Mega S with E3Dv6 hot end - revision 3. Updated exit geometry to alter angle downward slightly on the rear exhaust compared to Rev D.

Part cooling fan duct for Anycubic i3 Mega S with E3Dv6 hot end - revision 3. Updated directional (in X-Y) exhaust exit geometry compared to Rev C

Part cooling fan duct for Anycubic i3 Mega S with E3Dv6 hot end - revision 3. Updated  exhaust exit geometry to alter angle downward slightly compared to Rev C and Rev C v4.

Part cooling fan duct for Anycubic i3 Mega S with E3Dv6 hot end - revision 3. Updated exhaust exit geometry compared to Rev B
