“…In this regard, the log-normal distribution has been long-established (Gupta and Yan 2006) for fitting sediment data; however, better goodness-of-fit may be achieved by others, such as Rosin Rammler, gamma, GaudinSchuhmann, Broadbent-Callcott, Gaudin-Meloy and the Nukiyama-Tanasawa distribution (Holdich 2002;González-Tello et al 2008;Merkus 2009). …”

Purpose The development of mathematical models to accurately represent the particle size distribution (PSD) of sediment has been addressed by different authors. Here, we introduce the three-parameter Swrebec function as a tool to fit the PSD of sediments. Moreover, we also assess the physical meaning of the undulation parameter (b) in the function. Materials and methods We performed PSD by means of laser diffraction spectroscopy. Then, sediments were classified and the statistical parameters (mean, skewness, sorting and kurtosis) calculated using GRADISTAT software, according to the Folk and Ward's method. Subsequently, the Swrebec function (programmed in Matlab) was applied to the data and its goodness-of-fit were evaluated by means of the adjusted coefficient of determination (R 2 -Adj) and the root mean squared error (RMSE). The results obtained by Swrebec were also compared with other functions using the Ezyfit toolbox. Results and discussion The Swrebec model provided excellent correlations and low RMSE when fitting all grain size data. Furthermore, a correlation between b and both the skewness and RMSE was established. This indicates that the greater the asymmetry of the function, and therefore the larger the presence of coarse-grained particles, the lower the performance of the function. It was also observed that a change in the behaviour of all trends seems to occur at a b value of~4.5.Conclusions Results suggest that the studied function could be a simple approach for modelling PSD, with potential applications in soil and sediment science, geochemistry, sedimentology and coastal research modelling.

“…2) were performed with a particle laser diffraction analyzer (model Mastersizer 2000) which is conform to ISO 13320:2009. Based on the Rosin-Rammler-Sperling law [24], the instrument software get the volume distribution, the specific surface area and the uniformity factor [25]. The chemical compositions of concrete components reported by Table 1 were experimentally determined through atomic absorption spectrometry (ASS) and energy dispersive X-ray fluorescence (EDXRF) techniques.…”

“…The first series of calculations has been devoted to assessing the impact of droplet-sizedistribution parameters on the separation efficiency of the separator without hooks. A Rosin-Rammler model [8] for the particle-size-distribution analysis was used. Three cases were tested: the constants in the Rosi-Rammler models were equal to 2.25 and 4.52 and the case of monodisperse particles.…”

Abstract. This paper studied the droplet transport and deposition in the turbulent flow inside a wave-plate eliminator of the waste-heat utilisation complex (WHUC). The Lagrangian discrete particle approach was used to simulate the process of liquid separation from wet steam flow. Two different models for droplet-eddy interaction were tested using data from the available literature. The tested numerical model was used to predict the WHUC performance.
