Phase I

Contract Number: ----------
Start Date: 00/00/00    Completed: 00/00/00
Phase I year
1998
Phase I Amount
$65,000
The considerable importance of proper ventilation and air movement in livestock buildings has been well documented. The capital and operating costs associated with these air movements is also widely recognized. These factors, which are documented in the proposal, provide the motivation for the proposed efforts to adapt a demonstrated invention: 'the aerodynamic shroud' to agricultural ventilation fans. The aerodynamic shroud has been shown to increase the maximum flow rate and to reduce the system power consumption for automotive cooling fans. The proposed work is to bring these benefits to agricultural applications.

Anticipated Results/Potential Commercial Applications of Research:
: The technical efforts of this Phase I work will result in: i) an optimum shroud for a 36 inch ventilation fan and ii) the optimum method to pressurize the shroud for a given application. (The fan laws permit these optimum conditions to be scaled to other large fans 24

Phase II

Phase II year

Tunnel ventilation is an effective means of protecting and enhancing the productivity of livestock (especially swine and egg layers) in large scale confinement barns. The capital and operating costs for these fan installations typically represents a significant fraction of the total costs to the livestock producer.The Phase I research program has shown that significant improvements (ca. 40 percent in airflow and 10 percent in efficiency) can be obtained by the judicious use of active control flows. The Phase II proposal is to permit optimized ventilation systems to be designed using advanced CFD (computational fluid dynamics) methods. The CFD codes will be proof-tested using baseline data (first iteration) and used to define the predicted/optimized configurations: the second iteration. Experiments will confirm (or suggest modifications to) the latter.

Anticipated Results/Potential Commercial Applications of Research:
Digital Flow Technologies, Inc. will work in close collaboration with our commercialization partner: Aerotech, Inc. of Mason, MI in the development of the optimized system approach. The support provided by the partner is provided the understanding that the results of the Phase II work will be readily integrated into the Aerotech product line. Aerotech's experience as a leading manufacturer and supplier of top-end equipment ensures the marketing and sales resources to move the developed units into livestock production community.
