Experimental method for calculation of laminar burning velocity of paraffin gaseous fuel in closed vessel using data acquisition system

Abstract EN

The burning velocity is defined as the velocity at which unburned gases move through the combustion wave in the direction normal to wave surface.

It is used in many areas of combustion science such as in designing burners and predicting explosions. In this research a data acquisition system has been designed to measure the laminar burning velocity using a modern technique, which uses thermocouples as measuring sensors connected to a an interface computer.

The hardware has been designed to connect three groups of sensors to the computer.

A program has been used to access the interface and to acquire the huge measured data which is filtered through reading in a suitable manner.

The results made it possible to achieve an imperical equation can be used in evaluating laminar burning velocity of parraffin gaseous fuels, the expermintal investigations show acceptable computations compared with previous researches results.
