  2. 1. Numerical and Experimental Investigations of the Machinability of Ti6AI4V : Energy Efficiency and Sustainable Cooling/ Lubrication Strategies

    Author : Salman Pervaiz; Cornel Mihai Nicolescu; Hazim El-Mounayri; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloys; Energy consumption; Wear mechanisms; Finite element analysis; computational fluid dynamic analysis; Production Engineering; Industriell produktion;

    Abstract : Titanium alloys are widely utilized in the aerospace, biomedical,marine, petro-chemical and other demanding industries due to theirdurability, high fatigue resistance and ability to sustain elevateoperating temperature. As titanium alloys are difficult to machine, dueto which machining of these alloys ends up with higher environmentalburden. READ MORE

  5. 3. Evaluation of a cyclone gasifier design to be used for biomass fuelled gas turbines

    Author : Hassan Salman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : This thesis is a result of experimental studies carried out as a part of the efforts made in Sweden and within the European Union to develop a technology that will make it technically and economically possible to use biomass as a gas turbine fuel. The process that has been studied is based on cyclone gasification of biomass powder and no further cleaning of the product gas from the gasifier. READ MORE

  6. 4. Managing applications and data in distributed computing infrastructures

    Author : Salman Toor; Sverker Holmgren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Abstract : Over the last few decades, the needs of computational power and data storage by collaborative, distributed scientific communities have increased very rapidly. Distributed computing infrastructures such as computing and storage grids provide means to connect geographically distributed resources and helps in addressing the needs of these communities.

  7. 5. Large eddy simulation of combustion using linear-eddy subgrid modeling

    Author : Salman Arshad; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES-LEM; splicing; turbulent combustion; super-grid LES-LEM; CFD; linear eddy model; reaction-rate closure; large eddy simulation;

    Abstract : As emissions regulations are getting stricter and efficiency requirements of internal combustion engines (ICE) are increasing, different concepts to improve combustion are being investigated. For example lean stratified premixed combustion, homogeneous charge compression ignition (HCCI), use of more exhaust gas recirculation (EGR) to reduce NOx etc. READ MORE
