Modeling and Guidance of an Underactuated Autonomous Underwater Vehicle
Autonomous Underwater Vehicles (AUVs) have become an indispensable tool that is employed by an array of fields. From the inspection of underwater cables and pipelines, to the monitoring of fish pens and coral reefs, to the ...
Numerical simulations for the optimization of online wash systems for gas turbines
During gas turbine operation, large amounts of small particles are ingested along with the air inflow. As a result, the blade shape changes over time, hence affecting the air flow pattern and reducing efficiency. Field ...
Numerical Simulations of Drag-Reducing Devices for Ground Vehicles
The aim of the present study is to reduce the aerodynamic drag coefficient of ground vehicles. With the application of efficient drag reducing devices, aerodynamic drag is significantly reduced. This study analyzes numerically ...
CFD Based Airfoil Shape Optimization for Aerodynamic Drag Reduction
Commercial airplanes generally follow specific flight profiles consisting of take-off, climb, cruise, descend and landing. These flight profiles essentially change the freestream conditions in which the aircrafts operate. ...
Development of an Optimization Scheme for A Fixed-Wing UAV Long Endurance with PEMFC and Battery
Unmanned aerial vehicles (UAVs) and fuel cell industries are seeking to enhance the capability and performance of UAVs powered by fuel cells as propulsion systems. Tasks such as surveillance and land surveying increased ...
Flow Simulations of Axisymmetric Prolate Particles in a Cylindrical Pore
The motion of small particles in a fluid is a classical fluid mechanics problem. The present study investigates the motion of axisymmetric prolate spheroids and Cassini ovals of micro-scale through Newtonian and non-Newtonian ...
