The implicit Colebrook equation has been the standard for estimating pipe friction factor in a fully developed turbulent regime. Several alternative explicit models to the Colebrook equation have been ...

The Darcy-Weisbach equation is the most recommended equation for determining the pressure loss in pressurized pipes because of its wide applicability. However, one of the largest obstacles to ...

In this paper, we present an improvement of a mathematically equivalent representation of the Colebrook−White (CW) equation to compute friction factors for turbulent flow in rough pipes. This new form ...

The fractional diffusion equations can accurately describe the migration process of anomalous diffusion, which are widely applied in the field of natural science and engineering calculations. This ...

Abstract: An explicit analytical expression is proposed as an approximation of the generalised normalised diode equation. This function is simple, presents a correct asymptotic behaviour and offers a ...

Abstract: To address the stability constraints associated with small elements in the traditional explicit wave equation-based discontinuous Galerkin time domain (DGTD) method for multiscale modeling, ...

Structural equation modeling (SEM) is a powerful statistical approach for the testing of networks of direct and indirect theoretical causal relationships in complex data sets with intercorrelated ...
