Abstract

In this work 3D CFD analysis of a fluid flow problem within vertical ground heat exchanger is discussed. Both downward and upward pipes of the heat exchanger are made of polyethylene (PE100) and they are equipped with internal micro-fins. These fins form a sort of threads with the pitch varying between 1200 mm and 1600 mm. Both pipes (almost 250 meter long each) are connected at the lowest point either by standard U-turn or by specially designed bottom chamber. Two different water-ethanol solutions circulate within the pipes of the heat exchanger. Because of the heat exchanger length the whole computational domain was divided into three parts: inlet part, reversal or both pipes connection and remaining pipes for which pressure drops depend linearly on the pipe length. These three parts were analysed separately and obtained solutions have finally been coupled iteratively.
