1. Thermal comfort and energy in residential buildings in a cold climate
Abstract : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. READ MORE

2. Ventilation Flow Field Characteristics of a Hydro-Generator Model- An experimental and Numerical Study
Abstract : Hydro-generators are complex machines used to convert the mechanical energy of the water turbine into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process which will cause heat generation and temperature increase. Cooling systems are needed to remove this excess heat from hydro-generators. READ MORE

3. Development of Concentrating Photovoltaic-Thermal Solar Collectors
Abstract : Fossil fuels have greatly improved human living standards and saved countless lives. However, today, their continued use threatens human survival, as CO2 levels rise at an unprecedented pace to levels never seen during human existenceon earth. READ MORE

4. The indoor thermal climate in residential buildings after energy efficiency measures in a subarctic climate
Abstract : There is ongoing work related to the energy efficiency of residential buildings in the subarctic regions in northern Sweden. The focus is often on the reduction of energy usage and the economic aspects for the property owners. With the introduction of new technology and changes to the existing building, the indoor thermal climate is affected. READ MORE

5. Fluid Flow and Heat Transfer Simulations for Complex Industrial Applications : From Reynolds Averaged Navier-Stokes towards Smoothed Particle Hydrodynamics
Abstract : Optimal process control can significantly enhance energy efficiency of heating and cooling processes in many industries. Process control systems typically rely on measurements and so called grey or black box models that are based mainly on empirical correlations, in which the transient characteristics and their influence on the control parameters are often ignored.
