Through this work, we have analyzed wake to wake interactions between horizontal axis wind turbines located in line to each other. We have quantified wake interactions based on hot wire anemometric data and statistical correlations using a model wind farm fabricated inside a wind tunnel. The results of these measurements show that a high level of turbulent kinetic energy is generated at the region of intersection between rotor and stator wakes. Numerical models of wake interactions of wind turbines under varying turbulent inflow conditions using the actuator line technique and EllipSys3D Navier-Stokes solver were carried out to resolve dynamics of wake interactions. Our results showed good agreement with field measurements of wake deficit and turbulence intensity for inline and eccentric turbine arrangements.

Through this work, we have studied a thermoelectric generator-based waste heat recovery system with a low response time for fast energy generation under low and high direct normal solar radiations. Under direct normal radiation of 1000 W m-2, a TEG voltage up to~3 V has been observed within a saturation time of~900 s. A large temperature gradient (15000 K/m) is produced between hot and cold ends of the TEG module under a simple application of solid-fluid convective heat exchanger. Our results show the potential of remote heating and heat transfer for TEG power generation for small scale power emergencies.
