Empirical correlations relating the drag coefficient of spheres to the Reynolds number are
qualitatively reviewed with the focus on the presumed mathematical expressions used in the …

For an oil well to be said to have been successfully and conclusively drilled, the drilling fluid
lies at the heart of the solution. Therefore, the guarantee to solving issues in oil well drilling …

Genetic programming (GP; Koza 1992) is a biologically inspired machine learning method
that evolves computer programs to perform a task. It does this by randomly generating a …

The Multiphase Flow Handbook, Second Edition is a thoroughly updated and reorganized
revision of the late Clayton Crowe's work, and provides a detailed look at the basic concepts …

Accurate runoff prediction is vital in efficiently managing water resources. In this paper, a
hybrid prediction model combining complete ensemble empirical mode decomposition with …

The settling process of particles occurs in many natural and industrial processes and the
knowledge of drag coefficient and settling velocity of spherical and non-spherical particles is …

The knowledge of simple and relatively accurate closure equations for the drag coefficients
of nonspherical particles is very important for Eulerian multiphase numerical codes that …

Estimating groundwater level (GWL) is an important issue for planning and managing
available water resources. This study uses monthly data from 86 observation wells from …

The Colebrook–white equation is widely used in many fields, like civil engineering for
calculation of water distribution systems and in all fields of engineering where fluid flow can …

In the present study, the performance of the support vector machine for estimating vertical
drop hydraulic parameters in the presence of dual horizontal screens has been investigated …
