  2. 1. Aspects of Optimisation of Separation of Drugs by Chemometrics

    Author : Valérie Harang; Douglas Westerlund; Sven P. Jacobsson; Bo Karlberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; optimisation; separation; chemometrics; high performance liquid chromatography; electrodriven techniques; microemulsion electrokinetic chromatography; statistical experimental design; molecular modelling; chiral separation; cellobiohydrolase; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi;

    Abstract : Statistical experimental designs have been used for method development and optimisation of separation. Two reversed phase HPLC methods were optimised. READ MORE

  4. 2. Turbulent Boundary Layer Separation and Control

    Author : Ola Lögdberg; P. Henrik Alfredsson; Jens Fransson; Guido Buresti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow control; adverse pressure gradient APG ; flow separation; vortex generators; jet vortex generators; pulsed jet vortex generators; Fluid mechanics; Strömningsmekanik;

    Abstract : Boundary layer separation is an unwanted phenomenon in most technical applications, as for instance on airplane wings, ground vehicles and in internal flow systems. If separation occurs, it causes loss of lift, higher drag and energy losses. It is thus essential to develop methods to eliminate or delay separation. READ MORE

  5. 3. Vortex generators and turbulent boundary layer separation control

    Author : Ola Lögdberg; Henrik Alfredsson; Per-Åge Krogstad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent boundary layer separation; adverse pressure gradient; vortex generators; control of separation; Fluid mechanics; Strömningsmekanik;

    Abstract : Boundary layer separation is usually an unwanted phenomenon in most technical applications as for instance on airplane wings, on ground vehicles and in internal flows such as diffusers. If separation occurs it leads to loss of lift, higher drag and results in energy losses. READ MORE

  7. 5. Modelling phase separation in Fe-Cr alloys : A continuum approach

    Author : Thomas Barkar; John Ågren; Nele Moelans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

    Abstract : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. READ MORE
