Simulating water distribution patterns for fixed spray plate sprinkler using the ballistic theory
Ballistic simulation of the spray sprinkler for self-propelled irrigation machines requires the incorporation of the effect of the jet impact with the deflecting plate. The kinetic energy losses produced by the jet impact with the spray plate were experimentally characterized for different nozzle sizes and two working pressures for fixed spray plate sprinklers (FSPS). A technique of low speed p...
متن کاملA comparison of fixed and rotating spray plate sprinklers
A comparative study of two types of spray sprinklers was performed. Rotating spray plate sprinklers (RSPS) and fixed spray plate sprinklers (FSPS) were evaluated individually in open field conditions. The water distribution, wind drift and evaporation losses during the evaluations were measured under low, medium and high wind speed conditions with three nozzle diameters and two nozzle heights a...
متن کاملModelling Aspects of Sprinkler Spray Dynamics in Fires
S prinklers are used extensively in a variety of fire protection applications. These systems are required to perform effectively over a wide range of extremely harsh and complex operating conditions. The sprinkler performance depends on the initiation, formation, dispersion and surface cooling characteristics of the sprays created by these devices. The behaviour of sprinkler sprays is strongly ...
متن کاملModelling of Mean Drop Size in a Extraction Spray Column and Developing a New Model
In the present investigation the biosorption potential of rosa gruss an teplitz (Red Rose) Waste Biomass (RRWB) for the removal of Pb(II) and Co(II) from aqueous solutions was studied. The effect of different process parameters such as pH, biosorbent dose, biosorbent size, temperature, contact time, initial metal concentration and pretreatments on the biosorption capacity of this waste biom...
متن کاملA Mathematical Model of the Drag Component of a Sprinkler Spray Adjacent to Horizontal Smoke Vents
A mathematical model has been developed to investigate the effect of a sprinkler spray on adjacent horizontal smoke venting and in particular the water droplet drag component. The pressure difference across a roof vent and the volumetric flow of smoke vented are determined by considering the interaction between the drag force of the sprinkler spray and the buoyancy of the smoke layer in the spr...
