Reynolds averaged and large eddy simulations of the turbulent flow in a channel with inclined and V-shaped turbulators on the walls
(2012-07)
Turbine inlet air temperatures may exceed the melting points of the turbine blade material. Proper cooling processes increase turbine blade durability as well as the engine efficiency by allowing higher combustion temperatures ...
DNS of turbulent channel flow with inclined, continuous and segmented V-shaped turbulators
(2011-05)
The cooling system of the gas turbine blades plays a critical role in increasing the thermal efficiency and power output of advanced gas turbine engines. In fact, by increasing the heat transfer, the turbine blade can ...
Estudio teórico y experimental de modelos para cálculo y control de presiones sub atmósfericas durante flujo transitorio
(2004)
This research introduced MacCormack numerical scheme for the solution of the
governing equations of two-phase transient flow. The numerical solution included an
analysis of the behavior of the wave velocity under adiabatic ...
Wireless internet controlled surveillance robot
(2012)
Robotics has greatly facilitated an increasingly wide range of the applications of robots
in this age and it is also integrated in more and more areas. On the other hand, in this
fast-growing modern society, networking ...
Boundary layers affected by pressure fields of adjacent compressor blades: A numerical approach
(2018-05)
Reynolds Average Navier Stoke (RANS) models and Large Eddy Simulation (LES) model,
were used to simulate a two NACA 65-410 airfoil compressor cascade using an overset mesh. For
mesh validation, comparison of pressure, ...
Generation and dynamic control of air microbubbles subjected to a complex 3D acoustic field
(2016)
The purpose of this research is to verify that the translational movement of a microbubble in a complex three-dimensional geometry subjected to a standing acoustic field, can be predicted with the acoustic pressure gradient ...
Characterization of squeeze-cast AIB12/AI and AIB2/AI composites
(2009)
Aluminum alloys containing 2 and 4 wt.% copper reinforced with aluminum borides were successfully fabricated by squeeze casting employing squeezing pressures up to 62 MPa. The distribution of reinforcements in the composites ...
Water transport in the diffusion media of a proton exchange membrane fuel cell (PEMCF)
(2009)
The fuel cell is an electrochemical energy conversion device that produces electricity based on an electrochemical reaction. From the diverse types of fuel cell the proton exchange membrane fuel cell (PEMFC) has better ...
Static and dynamic analysis of a piping system
(2004-12)
An Investigation of flow-induced vibration is presented in this thesis. Three finite elements models for the pipe system were developed: a structural finite element analysis model with multi-support system for frequency ...
