A new approach for thermal performance calculation of cross-flow heat exchangers
(Elsevier B.V., 2005-08-01)
A new numerical methodology for thermal performance calculation in cross-flow heat exchangers is developed. Effectiveness-number of transfer units (epsilon-NTU) data for several standard and complex flow arrangements are ...

Physical–numerical parameters in turbulent simulations of natural convection on three-dimensional square plates
(2022-01-05)
Purpose: This paper aims to study, experimentally validate and select the main physical and numerical parameters of influence in computational numerical simulations to evaluate mean heat flux by natural convection on square ...
Testing viscoelastic numerical schemes using the Oldroyd-B fluid in Newtonian kinematics
(Elsevier B.V., 2020-12-15)
We focus here on using a Newtonian velocity field to evaluate numerical schemes for two different formulations of viscoelastic flow. The two distinct formulations we consider, correspond to either using a fixed basis for ...
Coupled Thermo-Hydro-Mechanical Numerical Modeling of Evolving Fractures in Rocks
(Springer, 2021-04-22)
We present a numerical technique capable of handling evolving fractures in rocks triggered by coupled thermo-hydro-mechanical (THM) phenomena. The approach is formulated in the context of the finite-element method (FEM) ...
A reduced order approach for probabilistic inversions of 3-D magnetotelluric data I: general formulation
(Wiley Blackwell Publishing, Inc, 2020-12)
Simulation-based probabilistic inversions of 3-D magnetotelluric (MT) data are arguably the best option to deal with the nonlinearity and non-uniqueness of the MT problem. However, the computational cost associated with ...
Numerical methods for elliptic partial differential equations with rapidly oscillating coefficients
(2003)
This paper presents two methods for the numerical solution of the classical homogenization problem of elliptic
operators with periodically oscillating coefficients. The numerical solution of such problems is difficult ...
On the compressive strength prediction for concrete masonry prisms
(SPRINGER, 2010)
The results of a combined experimental program and numerical modeling program to evaluate the behavior of ungrouted hollow concrete blocks prisms under uniaxial compression are addressed. In the numerical program, three ...
