Moisture Estimation in Cabinet Dryers with Thin-Layer Relationships Using a Genetic Algorithm and Neural Network

open access: yesMathematics, 2019
Nowadays, industrial dryers are used instead of traditional methods for drying. When designing dryers suitable for controlling the process of drying and reaching a high-quality product, it is necessary to predict the gradual moisture loss during drying ...

Numerical Study of Large-Scale Fire in Makkah’s King Abdulaziz Road Tunnel

open access: yesFluids, 2021
Tunnel fires are one of the most dangerous catastrophic events that endanger human life. They cause damage to infrastructure because of the limited space in the tunnel, lack of escape facilities, and difficulty that intervention forces have in reaching ...

The Bouncing Jet: A Newtonian Liquid Rebounding off a Free Surface [PDF]

open access: yes, 2007
We find that a liquid jet can bounce off a bath of the same liquid if the bath is moving horizontally with respect to the jet. Previous observations of jets rebounding off a bath (e.g.

Flow and air-entrainment around partially submerged vertical cylinders [PDF]

open access: yes, 2019
In this study, a partially submerged vertical cylinder is moved at constant velocity through water, which is initially at rest. During the motion, the wake behind the cylinder induces free-surface deformation. Eleven cylinders, with diameters from $D=1.4$
