  1. 1. An experimental investigation of flow in a Kaplan runner : steady-state and transient

    Author : Kaveh Amiri; Bjarne Børresen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Water turbines are since some years widely used for grid stabilization purposes according to their exceptional load variation capability which gives them the ability to compensate grid fluctuations initiated by the customer’s consumption or intermittent electricity production systems such as wind and solar power. Different renewable power generation technologies can be combined in mini-grids to electrify isolated villages and extend existing grid networks. READ MORE

  3. 3. Development of New Monte Carlo Methods in Reactor Physics : Criticality, Non-Linear Steady-State and Burnup Problems

    Author : Jan Dufek; Jan Wallenius; Waclaw Gudowski; Cheikh Diop; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; Nuclear physics; Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE

  4. 4. Process Utility Performance Evaluation and Enhancements in the Traditional Sugar Cane Industry

    Author : Eyerusalem Deresse Birru; Andrew Martin; Catharina Erlich; Hailong Li; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sugar cane; energy saving; heat loss; steady state; transient state; CO2 emission; absorption chiller; pellet; bagasse drying; energy perfor-mance; traditional mills; modern mills; waste water; surplus power; Energy Technology; Energiteknik;

    Abstract : The need to achieve sustainable development has led to devising various approaches for the efficient utilization of natural resources. Renewable energy technology and energy efficiency measures feature prominently in this regard, and in particular for industries such as sugar production:  the sugar cane industry’s eponymous feedstock is a renewable resource, and mills have potential for increased energy savings via improvements to cogeneration units, electric drive retrofitting, and other measures.

  5. 5. Steady-State Diffusion in Complex Amphiphilic Films

    Author : Christoffer Åberg; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; film formation; lung surfactant; skin surface pH; stratum corneum; responding membrane; diffusive transport; phase transition;

    Abstract : The relation between structure and diffusive transport at steady-state is investigated theoretically for amphiphilic systems. Amphiphilic systems typically show a large response to moderate changes in control parameters, such as temperature, osmotic pressure, and the presence of cosolvents and cosolutes. READ MORE
