New Research Supports Simulations of Airside Heat Transfer around MicroGroove Tubes, Says Copper Alliance
Now designers can simulate and optimize the performance of MicroGroove heat exchangers
New York, New York (30 September 2016) – According to the Copper Alliance, airside heat transfer around smaller diameter tubes now can be modeled with unprecedented accuracy.
Research supported by the International Copper Association (ICA) and conducted by Optimized Thermal Systems, Inc. (OTS) compares the performance of slit fins and louvre fins for smaller diameter (3 mm to 5 mm) copper tubes [1, 2].
Previously only the largest OEMs could afford to perform coil optimization through CFD modeling. Now, thanks to the Center for Environmental Energy Engineering (CEEE) at the University of Maryland and OTS, techniques for optimizing coil designs are available to users of CoilDesigner®, a highly customizable software tool that allows designers to simulate and optimize the performance of heat exchangers .
OTS works with coil designers around the globe to optimize heat exchanger geometry, including the use of smaller diameter tubes. CoilDesigner includes the latest heat transfer and pressure drop models published in the open literature and users also can plug-in proprietary models. OEM users can shorten product development costs and quickly bring products to market.
“Airflow around smaller diameter tubes faces less resistance than airflow around traditional tubes,” says Nigel Cotton, MicroGroove Team Leader for the International Copper Association. “Hence, such capability opens the door to new, more energy efficient, heat exchanger designs.”
