1. CFD Study of An Office Room Equipped with Corner Impinging Jet Ventilation
Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : A CFD validation study was made using corner supplied impinging jet ventilation operating in cooling mode. The air distribution system has two equilateral triangle shaped inlets placed 80cm above the floor at the two that share a common wall. The supply air was introduced at 2.26m/s. LÄS MER
2. A Fractional Step Zonal Model and Unstructured Mesh Generation Frame-work for Simulating Cabin Flows
Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningsläraSammanfattning : The simulation of physical systems in the early stages of conceptual designs has shown to be a key factor for adequate decision making and avoiding big and expensive issues downstream in engineering projects. In the case of aircraft cabin design, taking into account the thermal comfort of the passengers as well as the proper air circulation and renovation can make this difference. LÄS MER
3. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet
M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. LÄS MER
4. Experimental investigation of ventilation performance of corner placed stratum ventilation in an office environment
Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : Energy use in buildings account for about one third of the total global energy supply and contributes as much as 30% of the anthropogenic greenhouse gas emissions. It is estimated that energy use in buildings will increase to 67% by 2030. LÄS MER
5. Fundamental study on the effect of pulsative inflow on a small scale room model : Simulation of an innovative ventilation solution
Master-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknikSammanfattning : Simulation of a wall jet in an enclosure performed to predict the effect of pulsation flow on improving the performance of mixing ventilation systems which are routine practices in industry. Comparing two flows with equal amount for constant and pulsation modes, it was found out that the same global airflow pattern exists for both of the cases but with generation of more eddies and local periodically velocity variations for pulsation mode.
