1. 31. Do Clay Minerals affect the thickener operationin Chuquicamata mine, Calama, Chile?

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Chris Soto; [2020]
   Keywords : Mine; clay minerals; mineral processing;

   Abstract : Chuquicamata mine mineralogy has been studied performing both X-Ray Diffraction (XRD) and X-RayFluorescence (XRF) to determine whether there is any influence in the thickener operations. Thetargeted minerals were the clay group because of their detrimental effect on mining operations asmodify the rheology of the suspensions. READ MORE

3. 32. A Simulation of Landslide-Generated Waves Using a Fully Implicit ISPH

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : Kosei Nishida; [2020]
   Keywords : SPH; Landslide-generated waves; non-newtonian fluid; multiphase flow; Technology and Engineering;

   Abstract : Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. READ MORE

4. 33. Use of Rheological Properties to Predict Extrusion Parameters

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Moa Mård; [2019]
   Keywords : Polymer; Rheology; Extrusion;

   Abstract : Paxymer AB is a company that manufactures and sells flame retardants for plastics, based on their patented technology. The flame retardants are often sold as a master-batch that the customers mix into their own plastic products. Paxymer has two master-batches with the exact same formulation, but are produced with different temperature profiles. READ MORE

   Abstract : After the sewage wastewater is collected from different households and directed to the treatment plants, it goes through several processes, which are physical, chemical and biological. The different processes remove the contaminant, and produce a semi-solid material named sludge. Sludge has a huge amount of liquid. READ MORE

6. 35. Model of Thermal EHL Based on Navier-Stokes Equations : Effects of Asperities and Extreme Loads

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Marko Tošić; [2019]
   Keywords : ;

   Abstract : A common approach in numerical studies of elastohydrodynamic lubrication (EHL) is based on solving the Reynolds equation that governs pressure distribution in thin lubricant films. The Reynolds equation is derived from the Navier-Stokes equations by taking assumptions that are considered valid when the thickness of the lubricant film is much smaller than its length. READ MORE
