Optimal design of computer experiments for surrogate models with dimensionless variables [PDF]

open access: yesStructural and Multidisciplinary Optimization, 2017
This paper presents a method for constructing optimal design of experiments (DoE) intended for building surrogate models using dimensionless (or non-dimensional) variables. In order to increase the fidelity of the model obtained by regression, the DoE needs to optimally cover the dimensionless space.

Effects of Physical Parameter Range on Dimensionless Variable Sensitivity in Water Flooding Reservoirs [PDF]

open access: yesActa Mechanica Sinica, 2006
The similarity criterion for water flooding reservoir flows is concerned with in the present paper. When finding out all the dimensionless variables governing this kind of flow, their physical meanings are subsequently elucidated. Then, a numerical approach of sensitivity analysis is adopted to quantify their corresponding dominance degree among the ...

Dimensionless learning based on information

open access: yesNature Communications
Dimensional analysis is one of the most fundamental tools for understanding physical systems. However, the construction of dimensionless variables, as guided by the Buckingham-π theorem, is not uniquely determined.

Handling Dimensionless Groups in Dimensional Analysis

open access: yes, 2021
Buckingham’s Theorem indicates only the number of dimensionless groups; it is necessary to go into some concepts that allow a reduction of these groups to make the results useful.

A Novel Efficient Method of Estimating Suspended‐To‐Total Sediment Load Fraction in Natural Rivers

open access: yesWater Resources Research, 2023
Sediment transport load monitoring is important in civil and environmental engineering fields. Monitoring the total load is difficult, especially because of the cost of the bed load transport measurement.
