Analysis of short helical and double U-tube borehole heat exchangers: A simulation-based comparison

Zarrella, Angelo; Capozza, Antonio; De Carli, Michele - In: Applied Energy 112 (2013) C, pp. 358-370

This paper makes a comparative analysis between a helical-shaped pipe and a double U-tube ground heat exchanger. The two configurations were installed at a shallow depth and studied, since a depth limit is mandatory in some areas. When installed this way, the interaction between the ground...

Study on method of electricity and heat storage planning based on energy demand and tidal flow velocity forecasts for a tidal microgrid

Obara, Shin’ya; Morizane, Yuta; Morel, Jorge - In: Applied Energy 111 (2013) C, pp. 358-373

The rapid tidal current near a lake inlet is transformed into electrical energy with Darius-type hydraulic turbine generators. When the tidal power generation is insufficient, the stored excess electric power generated from midnight to early morning of a representative day is used. The balance...
