- Scope
- With many corporations and suppliers conducting development and validation tests at different Climatic Wind Tunnel sites@ there is an increasing need for a recommended best practice that defines a process by which climatic wind tunnels can be correlated. This document addresses the test methods and metrics used to obtain similar results@ independent of location@ for Heating Ventilation and Air Conditioning (HVAC) and Powertrain Cooling (PTC) development. This document should be used as a guideline to make sure key aspects of tunnel testing are covered when comparing various climatic wind tunnel facilities. The depth of the correlation program is ultimately influenced by program objectives. Therefore a correlation program@ for the intent and purposes of this document@ can range from just a few tests to a full analysis that involves multiple vehicle tests identifying limitations and statistical boundaries. Using recommendations in this document will eliminate most of the items that effect facility mismatch in a correlation program. Background With manufacturers and OEM??s conducting development and validation tests at different Climatic Wind Tunnel sites@ there is an increasing need to establish correlation between test facilities. Several climatic wind tunnel organizations and affiliations assembled to discuss a plan to determine what was necessary to complete a successful correlation program. It became obvious that first and foremost all groups involved must understand the variations in climatic wind tunnel design. As a result@ attention was diverted to a series of meetings dedicated to special topics@ presented by experts in the climatic wind tunnel industry. The information collected throughout these discussions is the foundation used in publishing this document.
