  2. 1. Experimental Studies of Effusion Cooling

    Author : Bernhard Gustafsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; laser-Doppler anemometry; infrared thermography; film cooling; flow visualization; full coverage film cooling; jet in crossflow; effusion cooling;

    Abstract : The desire to increase the efficiency of jet engines, has led to an increase in the temperature in the combustion chambers and in the turbine stage. There is thus an interest in efficient cooling methods. Film cooling and effusion cooling are often used where there is a great heat load. READ MORE

  4. 2. Two dimensions of student ownership of learning during small-group work with miniprojects and context rich problems in physics

    Author : Margareta Enghag; Hans Niedderer; Peter Gustafsson; Jonte Bernhard; Phil Scott; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ownership of learning; exploratory talks; physics learning; context rich problems; miniprojects; Naturvetenskapernas och teknikens didaktik; fysikdidaktik; Ämnesdidaktik; Subject Didactics; Physics; Fysik; NATURAL SCIENCES; Naturvetenskapernas och teknikens didaktik;

    Abstract : In this thesis the theoretical framework student ownership of learning (SOL) is developed both theoretically and with qualitative research, based on studies of small-group work in physics with miniprojects and context rich problems. Ownership is finally defined as actions of choice and control, i.e. READ MORE
