    Abstract : Dredging activities at ports and harbors are inevitable for safe navigation of ships and vessels. The outcomes of dredging activities are huge volumes of dredged materials, which can range from very fine and contaminated sediments to sands and gravels. The coarse sands and gravels can be directly used in civil engineering applications. READ MORE

  2. 2. Distributed thermal response tests New insights on U-pipe and Coaxial heat exchangers in groundwater-filled boreholes

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Abstract : U-pipe Borehole Heat Exchangers (BHE) are widely used today in ground source heating and cooling systems in spite of their less than optimal performance. This thesis provides a better understanding on the function of U-pipe BHEs and Investigates alternative methods to reduce the temperature difference between the circulating fluid and the borehole wall, including one thermosyphon and three different types of coaxial BHEs.

    Abstract : Dredging activities at Ports and Harbors are inevitable for the safe navigation of ships and vessels. Dredged material may range from very fine and contaminated sediments to sand and gravels. While, granular dredged material can be directly utilized in civil engineering applications, fine sediments may require further treatment before use. READ MORE
