This book focuses on cases and studies of interest to mechanical engineers and industrial technicians. The considered applications in this volume are widely used in several industrial fields particularly in the automotive and aviation industries. Readers will understand the theory and techniques which are used in each application covered in each chapter. Volume 2 includes the following topics: -Numerical investigation of turbulent slot jets with various nanoparticle shapes -Experimental study on a sweeping gas membrane distillation unit -Development of design processes for multi-spindle drilling using a neural network and expert systems -Experimental investigation of a new hybrid solar collector (PV/t) system -Theoretical study of the effects of combustion duration on engine performance -Effects of preheating temperature and fuel-air equivalence ratio on pollution control in hydrocarbon combustion -Numerical study of natural convection between two concentric ellipses with different shapes and imposed temperatures -Theoretical study of the geometrical parameters effect on the behavior of a solar chimney power plant -Numerical investigations of the effect of packed bed porosity on the flow behavior -Comparison between a conventional and a four-stage Savonius wind rotor The presented case studies and development approaches aim to provide readers with basic and applied information broadly related to mechanical engineering and technology.

Wind tunnels are facilities in which the wind is produced by fans or by compressed air to study and measure the action of the air flow around a solid. There are two basic types of wind tunnels: the closed-circuit and the open-circuit. Open-circuits draw air from the ambient environment and exhaust it back to the ambient after exiting the fan, while in closed-circuit, the air repeatedly circulates through the tunnel. The closed-circuit design delivers improved efficiency and generates less noise, but it is more expensive and more difficult to manufacture. Wind tunnels are typically used in aerodynamic research to analyse the behaviour of flows under varying conditions, both within channels and over solid surfaces. The present book focus on uses and developments of wind tunnels. It consists on nine chapters presenting different studies on the design, uses and developments of the wind tunnel in different applications like wind turbines, building and aircraft models. The presented case studies and development approaches aim to provide the readers, such as engineers and PhD students, with basic and applied studies broadly related to the wind tunnels and its applications.
