Numerical modelling of an experimental energy pile

Geothermal energy is a way of reducing the cost of energy. Deep geothermal energy systems extract heat from very deep soil layers where the temperatures are very high. Shallow geothermal energy systems are about 150 metres deep and they are used to store heat in the soil, to extract it later and use it for space heating. These shallow geothermal...

Numerical modeling of dam-reservoir interaction seismic response using the Hybrid Frequency–Time Domain (HFTD) method

The research work studies the fundamentals of the Hybrid Frequency-Time Domain (HFTD) method for dynamic analysis of structures, applied to the seismic analysis of dam-reservoir interaction systems. The theoretical consistency and accuracy of the HFTD method, based on the frequency domain Fourier analysis, is demonstrated through all the parts...
