... predominantly towards coagulation of marine particles (Burd 2013), in coastal regions, the turbulent shear of the fluid can cause both coagulation and breaking of aggregates until an equilibrium is achieved. Therefore, in this paper, we investigate the effects of turbulence of fluid on OMA size distribution...

... by using breakage models in which it is flexible riser system. The crusher controls the nodule size distribution to applied to study broad range of crusher for better understanding and enhance the pumping operations over a flexible riser system. We have optimization purposes. In this paper, Ab-T10 model...

... Abstract As an important parameter in slurry pipeline transportation, there are many definitions of critical velocity. The definition in this paper is the velocity when there is a stationary bed in the pipeline. The test sediment is divided according to the size distribution. Through the tests...

... behind detached breakwater which leads to the recovery process of coastal erosion (mangrove replanting activity). This paper discusses the sediment grain size distribution behind detached breakwaters from the assessment of the field activity and numerical approach. The existing detached breakwater...

... ABSTRACT Heavy marine icing often disturbs safe navigation of ships sailing in cold regions. We focus on impinging seawater spray to address icing on large vessels. We investigated the amount of seawater spray and the size distribution of seawater particles impinged on the R/V Mirai using...

... velocity and hydraulic gradient was obtained for the carbonate sand. To examine the effect of particle size distribution on the permeability, carbonate sand specimens with varied uniformity coefficients and curvature coefficients have been used in the tests. The observation of a significant dependency...

... is close to the amount of spray obtained by the SPC. We conducted observations of the seawater spray on icebreaker Shirase. The results show that the MRS can be used to measure the amount of seawater spray, and the SPC is useful to analyze the particle size distribution of spray. Introduction Marine...

... Abstract A unified model is developed for the prediction of particle size distributions in turbulent flow, including both droplets and bubbles. The final particle size is determined based on the fluid particle maximum stable diameter and its ratio with respect to the Sauter mean diameter...

... samples were conducted: constant-strain-rate test and creep test. The samples were formed by Toyoura sand and No.8 sand. The grain size distribution of No.8 sand is wider than that of Toyoura sand. It was clarified that the viscoelasticity of hydrate-No.8-sand specimen were stronger than that of hydrate...
