... ABSTRACT Dense slurry flow is a feature of the oil sands operation. Modelling of erosion in dense slurry flow under oil sands process conditions is challenging. Although several erosion models are currently used for upstream produced sand application under very dilute sand conditions...

... concentration. The thickness loss in the elbows measured using ultrasonic erosion probes has been reported. CFD modeling of the elbows in series has been carried out with the single particle erosion models reported by Oka et al. ( Wear, 2005 ), DNV (DNV RP o501), Grant and Tabakoff ( J. Aircraft, 1975 ) and E...

.... Hence it is important to reliably predict the erosion rates which will allow for design precautions to avoid problems. The current solid particle erosion prediction models are either empirical or semi empirical in nature and the suitability over wide ranges of operations is questionable. Erosion models...

... alternative erosion modeling tools and commercial options, including computational fluid dynamics (CFD) and mechanistic models. Simpler alternate API C-factors also have been implemented for many years, based on field experience. Tables in this paper, based on erosion testing, give allowable flow velocities...

... are analyzed and are compared to results from a model that calculates particle impact velocity and erosion rates. The results indicate that there is a direct correlation between outputs from sand detectors and the erosion model. Therefore, results from sand monitors can be interpreted using an erosion model...
