efficiency of geothermal energy as a renewable energy source: energy performance of energy pile and energy diaphragm wall

In recent years, with the growth of industry in human societies, the amount of energy consumption in the world has been increasing. on the other hand, the most consumed energy sources in the world are non-renewable energy sources that cause a lot of damage to the environment. geothermal energy is one of the sources of renewable energy that can be used by energy geostructures. one of the types of energy geostructures, which is a more famous model, is energy pile that is widely used in building. another model, which is considered a relatively newer concept, is energy diaphragm walls, which have been studied in recent years. in this research, using comsol software and the finite element method. this research investigates the thermal performance of energy piles and energy diaphragm walls with different modes and models of placement of heat exchange pipes using comsol software and the finite element method. the results show that, under the same conditions, energy diaphragm walls have slightly better thermal performance.
