Calculation and verification of formula for the range of sprinklers based on jet breakup length

Abstract: Jet breakup length is an important parameter which reflects the length of sprinkler range. Based on the linear instability theory, the dispersion equation of cylindrical jet was established and the theoretical value of jet breakup length was calculated. The jet breakup length and initial amplitude of surface wave were measured by applying the high-speed photography technology. Meanwhile, the numerical simulation was conducted by combining Level Set-VOF method for describing the jet breakup length to verify the… Show more

“…Lb is mainly related to the nozzle structure and jet velocity, which affects the initial position and state of the water droplets produced during the primary jet breakup. Different values of Lb are used to determine the landing position of water droplets and the resulting wetting patterns (Jiang et al 2018). Lb is measured through laser-induced fluorescence (LIF) (Charalampous et al 2009a,b) or is estimated photographically (Jiang et al 2019;Sridhara and Raghunandan 2010).…”

“…Nevertheless, the traditional LSM also shows poor conservation easily resulting in mass loss, thus affecting the accurate positioning of the interface leads to an appearance of wrong results. In order to improve the conservation of mass, in the convective phase of the level set, several hybrid methods have been employed, for instance, combining LSM with VOF to obtain VOF-LSM [19]. However, this algorithm will increase the complexity of computation and waste the advantages of LSM.…”
