Machine & Energy — Cooling Circuit Turbulence
Cooling Circuit Turbulence for injection molding operations.
Laminar cooling water insulates itself — a stagnant film hugs the channel wall and heat transfer collapses to a third of turbulent flow. Flow meters per circuit (not per manifold) are how good toolrooms catch the strangled loop behind every 'slow corner' of a mold.
Formula
Note: Starting-point process values — the resin grade's datasheet and an in-mold study govern. Verify with a gate-seal study and a cooling-time ladder on the actual tool.

About Machine & Energy — Cooling Circuit Turbulence
Machine & Energy — Cooling Circuit Turbulence computes the governing relationship Re = v·D/ν — target ≥ 10,000 in mold circuits live as you type. Laminar cooling water insulates itself — a stagnant film hugs the channel wall and heat transfer collapses to a third of turbulent flow. Flow meters per circuit (not per manifold) are how good toolrooms catch the strangled loop behind every 'slow corner' of a mold. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Machine & Energy — Cooling Circuit Turbulence
- 1Enter your values — Channel diameter, Flow per circuit, Water kinematic viscosity (sensible defaults are pre-filled).
- 2Read the live results: Reynolds number.
- 3Check the "with your numbers" line to see Re = v·D/ν — target ≥ 10,000 in mold circuits substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
