1. Heat Transfer and Hydrodynamics in Falling Film Evaporation of Black Liquor
Abstract : The evaporation plant is one of the major steam consumers in kraft pulp mills, which are the dominant type of chemical pulp mill in Sweden. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. READ MORE

2. Packed-Fluidized Bed Reactors – Batch Experiments and Fundamental Modeling with Random Metal Packings
Abstract : The aim of this work is to investigate the effect of random packings on heat and mass transfer phenomena, when applied in bubbling fluidized beds. For this purpose, first, the heat transfer coefficient to a horizontal tube submerged in a fluidized bed containing various types of random packings was investigated. READ MORE

3. Combustion, Fluid Dynamics and Heat Transfer in Oxy-fuel and Air-Fired CFB boilers
Abstract : The studies described in this thesis develop and encode modeling tools for the design and scale-up of oxy-fuel circulating fluidized bed (CFB) boilers across a wide range of operational conditions. The modeling comprises fluid dynamics, combustion, and heat transfer and uses expressions that are proposed in this work or derived from the literature, together with experimental data obtained under both oxy-fuel-fired and air-fired conditions.

4. Radiative Heat Transfer in Suspension-Fired Systems
Abstract : Radiation is the dominating heat transfer mechanism in most furnaces, and the radiative properties of combustion products represent important aspects regarding its suitability as a heat source. However, fuel and energy markets are undergoing rapid changes due to increasing concerns related to the security of supply and increased global warming. READ MORE

5. Numerical predictions of heat-transfer applied to electrical machines
Abstract : In order to meet the need for increased electrification, and at the same time reduce the total demand for electric energy, behavior change and technological innovation is needed. Over the decades power density of electric motors have increased, leading to increased demands on the cooling system design and performance. READ MORE
