Applications of a Dynamic Three-dimensional Numerical Model for Borehole Heat Exchangers
Common approaches to the simulation of Borehole Heat Exchangers (BHEs) assume heat transfer in circulating fluid and grout to be in a quasi-steady state and ignore fluctuations in fluid temperature due to transport of fluid through the loop. However, the dynamic responses of circulating fluid and BHEs have important implications for systems design under some circumstances. This paper presents a...

متن کاملThermal Performance of Borehole Heat Exchangers
An important issue in the design of systems using borehole heat exchangers is to find costeffective methods to construct the borehole heat exchanger so that heat can be injected or extracted from the ground without excessive temperature differences between the heat carrier fluid and the surrounding ground. This paper presents an overview of experiences and current activities in this field.
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Numerical Modelling of Solar Heat Storage Using Large Arrays of Borehole Heat Exchangers
The storage of surplus heat in the underground and retrieval when required is a promising method for optimizing the energy efficiency of new housing estates. A new approach for the coupled numerical modelling of such problems will be presented. Here, the energy simulation software TRNSYS is directly coupled with the finite element subsurface flow and transport simulation software FEFLOW. This w...
