Air Flow Mas Sensor

This book develops an analysis of the air entrainment processes in free-surface flows. These flows are investigated as homogeneous mixtures with variable density. The variations of fluid density are caused by the non-uniform air bubble distributions and result from a turbulent diffusion process. Several types of air-water free-surface flows are studied: plunging jet flows, open channel flows, and water jets discharging into air. Each configuration can be characterised as a high-velocity free-surface flow with turbulent shear layers and large air bubble contents. Experimental observations confirm the concept that the air-water mixture behaves as a homogeneous compressible fluid in each case.

This book sets down the fundamentals of the theory and measurement of building ventilation and describes the various techniques for predicting and measuring ventilation. It addresses both envelope flows and internal air motion. The first part of the book is primarily concerned with physical descriptions and theoretical models: starting with an overview of the basic mechanisms and characteristics of envelope flows, it then addresses the treatment of the flow characteristics of individual openings and mathematical models for complete building envelopes. Theories for internal air motion are then discussed in detail: mechanisms of mass transport in terms of air motion and age distribution, primary air flows in isolation, resulting flows in enclosed spaces, and flows through large internal openings. The second part, concerned with measurement techniques both at full scale and at model scale, begins with techniques for determining flow characteristics of envelope openings. The use of tracer gases in the study of age distribution and ventilation efficiency is dealt with in detail. Scale modelling for investigating both envelope flows and internal motions is also addressed. The final chapter deals with Computational Fluid Dynamics, since one of its main applications is an alternative to conventional experimental techniques. Natural ventilation is re-emerging as an alternative to mechanical systems in some commercial buildings and both natural and mechanical ventilation are dealt with in detail.

Flow sensor - A flow sensor is a device for sensing the rate of fluid flow. Typically a flow sensor is the sensing element used in a flow meter, or flow logger, to record the flow of fluids.

Mass flow sensor - A mass flow sensor responds to the amount of a fluid (usually a gas flowing through a chamber containing the sensor. It is intended to be insensitive to the density of the fluid.

Air traffic controller - Air traffic controllers are persons who operate the air traffic control system to expedite and maintain a safe and orderly flow of air traffic and help prevent mid-air collisions. They apply separation rules to keep each aircraft apart from others in their area of responsibility and move all aircraft efficiently through 'their' airspace and on to the next.

Air curtain - *An air curtain is a method of containing oil spills. Air bubbling through a perforated pipe causes an upward water flow that slows the spread of oil.
