This thesis is part of a larger project that will demonstrate the feasibility of powering a commercially sized 7.5-ton cooling system. Excess cooling will be stored thermally using ice. This system has the potential to be used in military bases to reduce energy costs and fossil fuel consumption. A scaled down version would be suitable for data centers and forward operating bases where the transport of fuel can be costly and dangerous. The system will be built and operated at the Turbopropulsion Laboratory (TPL) of Naval Postgraduate School. This thesis concentrates on the choice and location of wind turbines used to power the cooling system. A simulation of Building 216, which is the planned site of the cooling system, was performed. A wind flow analysis found that optimum placement of the wind turbines is at the front of the south end of the building. The method for placing the wind turbines is outlined and applicable to other structures. Vertical Axis Wind Turbines (VAWTS) were found to be the most suitable for site location. A transient analysis of the VAWTS was necessary to accurately simulate their performance. This supported the selection of a three-bladed helical VAWT design. Further simulations of wind turbine separation showed some beneficial effects of close spacing.
