Additionally, based on the available literature he presented an overview of recognized optimum droplets diameters in the context of ability to cool down fire environment. Abstract This paper presents studies on the influence of the nozzle tilt angle on the distribution of water droplets diameters in a spray generated by the Turbo Master 52 nozzle. You could not be signed in. Estimation of spraying was in fact impossible mainly due to air turbulence and fact that not all droplets reaching the probe passed through the probe opening and were counted by the system. Grzesiek Mazur added it Dec 23, His experiments resulted not only in many valuable conclusions, but most of all revolutionized firefighting of that time.

Studied water nozzle; 2. Triple Massey products vanish over all fields. Below a detailed analysis grouped based on the above mentioned parameters is wlodarsi.

Zarzycki, Fluid mechanics in environmental engineering [Mechanika plynow w inzynierii srodowiska], Warszawa, in polish. Naturally it gave an impetus for the development wlodarwki the technical firefighting protection systems. Little later, at the end of 70's of the 20th century, the studies of the US navy created the foundation for the present firefighting water installations in the buildings [2]. Want to Read Currently Reading Read. Nowadays, studies on sprays wlodraski conducted by the American firefighter - instructor Paul Grimwood, who analyses mainly internal fires [7,8].

Set of electrical pumps connected in series; However, in his publications he specified also among others theoretical and practical ability of water cooling. Bielecki, Fundamental of fire-fighting [Podstawy taktyki gaszenia pozarow], Cracow, in polish.

It means that with the increasing nozzle tilt angle the degree of atomization decreases. Kolman, Study on influence of same geometric parameters of the nozzle and supply pressure on the spray parameters, Master thesis SGSP, Warszawa, in polish.

Their main objective was optimization of water stream parameters with regards to firefighting actions. Additionally, based on the available literature he presented an overview of recognized optimum droplets diameters in the context of ability to cool down fire environment.

Kapel added it Aug 08, Grimwood as a practitioner, based on many years of experience, focused mostly on practical aspects of the use of water streams in his studies, such as e. Open Preview See a Problem? Pieces of fire hoses W; However, there are still missing works on sprays generated by the nozzles in the real conditions, and it should be stressed that it is especially important in a practical aspect, as the firefighting efficiency reflects duration of the fire.

Summarizing, it should be stressed that the presented studies although have allowed for analysis of the influence of the tilt angle of the nozzle on the distribution of droplets diameters generated by the nozzle in the spray, however have not covered the whole subject. Probe of AWK D analyzer; Therefore, since many years numerous research institutes and even firefighters taking part in the firefighting actions on a daily basis, have conducted multiple studies on the effective use of water.

Special software AWK, working in Windows environment enables not only the reading of the results, but also online monitoring of visualization of the subsequently received drops spectrums during the measurements. Arithmetic average of average volume diameters of droplets Dv.

Alignment of the measuring points and their numbering wlodraski presented in Fig.

It means that the droplets generated by the studied nozzle have poor firefighting properties, especially low level of receiving heat. Studies on the spray were conducted according to the following measuring procedure: Deviation coefficient from the optimum diameter WSO From the data listed in tab.

Setting input parameters in AWK software; 3.

Arithmetic average of volume mean diameter of droplets Dv From the data included in tab. Studies on influence of the nozzle tilt angle on the distribution of droplets diameter in the spray generated by the selected Turbo Master 52 water nozzle was carried wlodarsji by the droplet spectrum analyser AWK D manufactured by KAMIKA Instruments [10]. The obtained results are presented in a tabular and graphical form. Values of arithmetic average of average volume diameters of droplets Dv for three different flow rates and spray angle.
