Experimental investigation of load exerted on a double-cone insert and effect of the insert on pressure along walls of a large-scale axisymmetrical silo
Ding, Songxiong; Dyrøy, A.; Karlsen, M.; Enstad, Gisle; Jecmenica, Mladen (Journal article; Peer reviewed, 2011-03-03)Applications of flow aid devices (commonly referred as inserts) improve the silo discharging mode. Considerable efforts have been made in finding best configurations between the inserts and silos to achieve the optimal ... -
Firefly optimization and mathematical modeling of a vehicle crash test based on single-mass
Klausen, Andreas; Tørdal, Sondre Sanden; Karimi, Hamid Reza; Robbersmyr, Kjell G; Jecmenica, Mladen; Melteig, Ole (Journal article; Peer reviewed, 2014)In this paper mathematical modeling of a vehicle crash test based on a single-mass is studied. The model under consideration consists of a single-mass coupled with a spring and/or a damper. The parameters for the spring ... -
Mathematical Modeling and Optimization of a Vehicle Crash Test based on a Single-Mass
Klausen, Andreas; Tørdal, Sondre Sanden; Karimi, Hamid Reza; Robbersmyr, Kjell G; Jecmenica, Mladen; Melteig, Ole (Chapter, 2014)In this paper mathematical modelling of a vehicle crash test based on a single mass is studied. The models under consideration consist of a single mass, a spring and/or a damper. They are constructed according to the ... -
On Detection of Yaw and Roll Angle Information for Vehicle Oblique Crash using Hough Transform
Tørdal, Sondre Sanden; Klausen, Andreas; Karimi, Hamid Reza; Robbersmyr, Kjell G; Jecmenica, Mladen; Melteig, Ole (Chapter, 2014)When performing vehicle crash tests, it is common to capture high frame rate video (HFR) to observe the vehicle motion during the impact. Such videos contain a lot of information, especially when it comes to geometric data. ... -
Piping Components: An Analysis of the Critical Dimensions
Anderson, Gwen; Gjerde, Ida Helene; Helgesen, Sondre Luca; Jecmenica, Mladen; Thapa, Rajan Kumar (Peer reviewed; Journal article, 2020)Pipe components such as elbow, tees, and weldolets are produced at various places in the world. Although the component is produced in accordance with standard ASME (American Society of Mechanical Engineers) B16.9, measurements ... -
Simulation and optimization of screw feeder in a bubbling fluidized bed gasification reactor
Thapa, Rajan Kumar; Vaa, Trym Fehn; Vaa, Oddvin; Jaiswal, Rajan; Jecmenica, Mladen (Journal article; Peer reviewed, 2022)A fluidized bed biomass gasification reactor is used to produce syngas from biomass and municipal wastes. Gasification is a flexible technology where many different types of feedstocks can be used. The University of ...
