A Prediction of Energy Piles’ Long-Term Operation Using a Coupled Thermo-Hydro-Geomechanical Model

T. Vu [1], L. Medina [1], D. de la Cruz [1], J. Ramirez [1], B. Xu [1]
[1] University of Texas - Rio Grande Valley, Edinburg, TX, USA

An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... Per saperne di più

由于在亚波长成像方面的潜在应用,双负声学超材料(同时具有负的有效密度和负的有效模量)受到了广泛关注。然而,已有的单带双负声学超材料的带宽限制了它的广泛应用。为了扩展双负带的带宽,电磁超材料中引入了多带双负超材料。最近,声学超材料研究人员设计了多带单负超材料。显然通过组合多带负有效密度和多带负有效模量超材料单元能够实现多带双负,可是单元间的阻抗不匹配影响声波的透射率。本文提出基于单负的亥姆霍兹共鸣器单元通过波导耦合实现多带双负的声学超材料单元。我们利用两个亥姆霍兹共鸣器耦合实现负密度和负模量的重叠,通过增加亥姆霍兹共鸣器实现多带双负超材料单元 ... Per saperne di più
