1. 1. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Julia Ahlbom; [2023]
   Keywords : Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

   Abstract : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

3. 2. Modeling of the trajectory of ice thrown from a wind turbine

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Elena Rocchi; [2023]
   Keywords : Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

   Abstract : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

4. 3. Propulsion modelling of a generic submarine propeller

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gustav Boman; [2023]
   Keywords : OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

   Abstract : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. READ MORE

5. 4. Design Optimization of Savonius Wind Turbine using CFD Simulations

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Vatsalkumar Manavar; [2023]
   Keywords : Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

   Abstract : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

6. 5. Numerical modeling of airflow on the cathode-side of a bipolar flow plate : How the formed geometry affects the pressure drop and flow distribution in a hydrogen fuel cell

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Olivia Johansson; [2023]
   Keywords : Performance; Cross-sectional geometry; Computational fluid dynamics;

   Abstract : Climate change and rising temperatures is a well-known problem. To tackle global warming a transition from fossil fuels to renewable and reliable energy sources is necessary. Hydrogen, in fuel cells, is proposed to replace diesel and gasoline in the transport sector. READ MORE
