Air Flow Meter Mass Air Sensor

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.

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.

Mass air meter - A Mass Air Flow meter (MAF meter) meter is one of the most important components of an electronically controlled internal combustion engine. The MAF meter's job is to keep the electronic control unit (ECU) informed of the amount of air flowing into the engine.

SIFT-MS selected ion flow tube mass spectrometry - Selected ion flow tube mass spectrometry is a sensitive and quantitative mass spectrometry technique for trace gas analyses using chemical ionisation of sample trace gases by selected positive ions during a well-defined time period along a flow tube. Absolute concentrations of trace compounds in humid air or breath are calculated in real time from the reagent and product ion signal ratios without the need for calibration using standards.

Density of air - The density of air, ρ (Greek: rho) (air density), is the mass per unit volume of Earth's atmosphere, and is a useful value in aeronautics. In the SI system it is measured as the number of kilograms of air in a cubic meter (kg/m3).

Mass airflow sensor - A mass airflow sensor (MAF) determines the mass of air flowing through a conduit. This is generally achieved by using heated wires in the airstream.
