Wilhelm Kalveramermal Heat Pumps (GHPs) are tools that can extract heat from subsoil, surface water bodies, or groundwater. In Colombia, geothermal energy is one of the least developed and known non-conventional renewable energy sources. To reduce the operating costs associated with the cooling at 3 °C of a flower’

Wilhelm Kalveramsing concepts in renewable energy. In this study, the efficiency to extract the energy from the incoming water flow when using a submerged asymmetric airfoil, NACA 1412, is investigated. This moves through a steady laminar regime, (Re = 1100), with forced Heave and Pitching motion. A mapping of effi

For example, the Rankine cycle is considered the best thermodynamic cycle for converting solar thermal energy into electrical energy. In this study, the variation
