Burger & Brown Engineering Inc. has announced several enhancements to its online Turbulent Flow Calculator, which was created as a reference for injection molders to help determine a target cooling channel flow rate, as a starting point for more efficient mold cooling.
New features include the availability of elevated water temperatures and ethylene glycol percentage input. By changing the percentage of ethylene glycol content, the Turbulent Flow Calculator demonstrates the big increase in flow rate needed to achieve turbulent flow — which is particularly significant when coolant temperature decreases in combination with an increase in ethylene glycol content.
Burger & Brown gave special attention to add input coolant temperatures of up to 650° F, with no ethylene glycol
Also, you can select metric or imperial units, and a Turbulent Flow Value Curve was added as a ready reference, along with Turbulent Flow Basics.
Burger & Brown, based in Grandview, Mo., provides the turbulent Flow Calculator as a free online service to the injection molding industry, as a result of the firm's ongoing research and development in the area of Scientific Cooling.
