A computationally efficient pseudo-3D model for the numerical analysis of borehole heat exchangers

Modeling the Translocation and Transformation of Chemicals in the Soil‐Plant Continuum: A Dynamic Plant Uptake Module for the HYDRUS Model

“…A classic example is to perform a sensitivity analysis on the model to investigate the impact of different parameters on some variables of interest. The sensitivity analysis is frequently used in modeling studies under different settings and aims (e.g., Brunetti et al, 2016;Brunetti et al, 2017;Brunetti, Šimůnek, & Bautista, 2018;Brunetti, Šimůnek, Turco, & Piro, 2018). In the present study, we apply a global sensitivity analysis to identify the most important factors among soil, plant, and chemical parameters that drive the accumulation of CBZ in spinach shoots.…”

“…Numerical models from vadose zone hydrology, which have been used extensively in the last decades (Jarvis & Larsbo, 2012;Šimůnek et al, 2016), offer great opportunities to head in this direction. In particular, Richards-based approaches have been used successfully in many applications and scientific fields (e.g., Brunetti et al, 2017Brunetti et al, , 2019Brunetti, Porti, & Piro, 2018;Brunetti, Šimůnek, & Bautista, 2018;Cheyns et al, 2010, Hanson et al, 2006, Jellali et al, 2016. Nolan et al (2005) compared the performance of the Richards-based and tipping bucket models in reproducing measured breakthrough curves of bromide and atrazine from two experimental facilities in Merced, California, and White River Basin, Indiana, respectively.…”

A hybrid finite volume-finite element model for the numerical analysis of furrow irrigation and fertigation

“…The mesh sensitivity analysis is used to examine the effects of the coarse spatial discretization on the results of the model. The analysis reveals that the model guarantees a sufficient accuracy even for larger mesh sizes, thus suggesting its application as a lower fidelity surrogate in computationally intensive statistical analyses (e.g., Brunetti et al, 2017aBrunetti et al, , 2017b.…”

Improving computational efficiency of numerical modelling of horizontal ground source heat pump systems for accommodating complex and realistic atmospheric processes

“…Cullin and Spitler (2011) developed a methodology for determining the duration of the shorter timestep and the magnitude of the corresponding load, which increases the performance of heat exchanger design tools that incorporate a "hybrid timestep" approach. Brunetti et al (2017) proposed a pseudo-three-dimensional (3D) model, which combines a one-dimensional (1D) description of the heat transfer in the buried tubes of the exchanger with a two-dimensional (2D) description of the heat transfer and water flow in the surrounding subsurface soil, to reduce the computational cost for the numerical analysis and interpretation of thermal response tests (TRTs). Fang et al (2018) developed a software package based on the finite difference method for thermal analysis of deep borehole heat exchangers (DBHEs), and the computation efficiency is increased by using an algorithm for the direct solution of resulted algebraic equation set.…”
