  1. 26. Three-way catalyst calibration and system modelling for CNG engine exhaust aftertreatment

    University essay from KTH/Kemiteknik

    Author : Khyati Parikh; [2022]
    Keywords : Three-way catalysts; 1D-Modelling; Kinetic parameters; Calibration; AVL Cruise M; Trevägskatalysatorer; 1D-modellering; Kinetiska parametrar; Kalibrering; AVL Cruise M;

    Abstract : Detta projekt behandlar metodutveckling för att modellera en trevägskatalysator som skulle kunna användas vidare för att uppskatta utsläppen från en Ottomotor. Modellen är byggd i AVL Cruise M för att bestämma omvandlingarna för de tre lagstiftade föroreningarna kolmonoxid, kväveoxider (NOx) och metan baserat på reaktioner som sker i trevägskatalysatorer.

  3. 27. Aeroengine transients in altitude test facility

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Baptiste VILLENEUVE; [2022]
    Keywords : ;

    Abstract : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. READ MORE

  4. 28. Finite Difference Approximations for Wave Propagation

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Sebastian Lindqvist; [2022]
    Keywords : Finite Difference; Maxwell’s equations; wave propagation; advection equation; partial differential equations;

    Abstract : Finite difference approximations are methods for solving differential equations by approximating derivatives. This work will begin with how to solve a partial differential equation (PDE) called the advection equation, ut + cux = 0. READ MORE

  5. 29. Impact of Extreme River Flows on Bridges An Application to River Lagan in Ljungby Municipality, Sweden Using HEC RAS

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Assad Mohammad Tahir; [2022]
    Keywords : HEC RAS; Extreme River Flow; River Bridges; Ljungby; Lagan; Climate Change.; Technology and Engineering;

    Abstract : The role of bridges in the transportation network has become increasingly important as they ensure the smooth and safe passage of people and goods across rivers and other bodies of water. Flowing water impacts bridges over rivers primarily in two ways: (1) Hydrodynamic forces that directly impact the structure and (2) scouring at the pier and abutment, including contraction scour.

  6. 30. Composite timber structures – Ribbed plate design : Evaluation of existing and development of new design methods

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Cristoffer Mård; [2022]
    Keywords : Ribbed plates; CLT; gamma-method; Timoshenko-method; shear analogy-method; FE-models; RFEM; Abaqus;

    Abstract : Ribbed plates comprising cross-laminated timber slab, CLT, with glulam beams allow for increased span length compared to pure CLT slabs. At the moment the Eurocodes do not provide any recommendations to design a CLT plate or a ribbed plate. There are handbooks for designing ribbed plates. READ MORE
