Performance Analysis of Hot-wire Air Flow Meter Under Normal Engine Operating Condition

A hot air driven thermoacoustic-Stirling engine

The wire-mesh sensor as a two-phase flow meter

A novel gas and liquid flow rate measurement method is proposed for use in vertical upward and downward gas–liquid pipe flows. This method is based on the analysis of the time history of area-averaged void fraction that is measured using a conductivity wire-mesh sensor (WMS). WMS measurements were collected in vertical upward and downward air–water flows in a pipe with an internal diameter of 3...

Air Mass Flow Analysis for SI Engine: EGR and Scavenging

In order to lower the Nitrogen Oxides (NOx) concentration in internal combustion engine emissions and to improve performance, Exhaust Gas Recirculation (EGR) and Scavenging mechanism are introduced. EGR recirculates a fraction of the exhaust gas back into the cylinders, thus diluting the intake air. This lowers the maximum combustion temperature and, since the formation of NOx is heavily depend...

Thermal MEMS flow meter for gaseous working fluids on the basis of the hot-wire thermoanemometric sensor

This paper describes the main principles of constructing innovative MEMS flow meters for gaseous working fluids. MEMS flow meter contains hot-wire thermoanemometrisc sensor which response to the temperature change caused by convective working fluid heat transfer from a hot-wire. The advantages of using hot-wire thermoanemometric sensors were analyzed. The main emphasis of this work is on speed,...

Evaluating The Performance of ANGEL Flow Meter

This technical report gives detail on the results obtained from evaluating the ANGEL Flow Meter (FM) performance. Evaluation metrics include packet loss, CPU and memory usage and the robust of the hash algorithm employed. It has been shown that the FM’s suffered packet loss (more than 10%) when coping with approximately more than 30,000 packets per second and 30,000 flows per second. There has ...
