Experimental Results in DBD Plasma Actuators for Airflow Control

41st Plasmadynamics and Lasers Conference, 2010
In this work several plane dielectric barrier discharge actuators had been experimentally investigated. Each actuator is constituted by a planar electrode pair separated by a dielectric. Several actuator geometries, dielectric materials, and a.c. supply voltages and frequencies have been utilized.

Gas Turbine Airflow Control for Optimum Heat Recovery

Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; Process Industries; Technology Resources; General, 1982
Gas turbines furnished with heat recovery equipment generally have maximum cycle efficiency when the gas turbine is operated at its ambient capability. At reduced gas turbine output the cycle performance can fall off rapidly as gas turbine exhaust temperature drops, which reduces the heat recovery equipment performance.

Airflow control by non-thermal plasma actuators

Journal of Physics D: Applied Physics, 2007
Active flow control is a topic in full expansion due to associated industrial applications of huge importance, particularly for aeronautics. Among all flow control methods, such as the use of mechanical flaps, wall synthetic jets or MEMS, plasma-based devices are very promising.

Control of Airflow Noise From Diesel Engine Turbocharger

SAE Technical Paper Series, 2011
<div class="section abstract"><div class="htmlview paragraph">Turbocharger is one of the main parts for high power and low fuel consumption. But due to high RPM of turbocharger causes noise problem. Flow in the turbocharger is very fast and unsteady so it's very hard to estimate the noise and to reduce.

Developing Controlled Airflow Technology for Airbus Wing

Aircraft Engineering and Aerospace Technology, 1986
AIRFLOW over an aircraft wing gives lift — but also produces drag. For this reason the aerodynamicist always tries to improve the lift‐to‐drag ratio — a value which quantifies the aircraft's aerodynamic quality — in order to reduce fuel consumption.

Drivecycle Benefits of Controlling Airflow with the SuperTurbo™

SAE Technical Paper Series, 2018
<div class="section abstract"><div class="htmlview paragraph">The SuperTurbo™ is a driven turbocharger that uses a high-speed traction drive combined with a CVT (Continuously Variable Transmission) or electric motor to provide additional power to or from the turbo shaft.

Control of Ventilation Airflow for Tunnel Fire Safety

Combustion Science and Technology, 2000
Behavior of fire-induced heat and smoke movement in a longitudinally ventilated model tunnel is studied experimentally. A gas burner is used as fire source. Ventilation velocity, heal release rate, temperature distributions arc measured under quasi-steady conditions.

Dynamic Control of Airflow Balance in Data Centers

ASME 2019 International Technical Conference and Exhibition on Packaging and Integration of Electronic and Photonic Microsystems, 2019
Abstract Efficient cooling of data center infrastructure is an important way to reduce total energy consumption. Containment, with separation of hot and cold airflows has allowed significant increase in efficiencies. However, balancing the airflow, so that IT equipment in an aisle only receives the cooling airflow that that aisle needs ...

A Radio-Command-Control Puffer for Studying Airflow*

Bulletin of the American Meteorological Society, 1955
A system is described with which air flow in the lower one or two thousand feet of the atmosphere can be studied by the use of a radio-command-control smoke puffer. Several applications of this system are proposed in connection with balloon sounding techniques.

Adaptive PID Control Application for an Airflow Monitoring System

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">This paper discusses the application of adaptive control, using a set of self-tuning PID control laws and a recursive least squares parametric identification method with a variable forgetting factor. This adaptive controller has been developed and applied to a computer simulated airflow monitoring system to ...
