This work describes the development and the application of a computer-based vehicle simulator. Such real-time simulation software is currently used in our Department as a tool for optimizing the design of a racing car, namely a single-seat vehicle for the Continue reading
In this work, a flow reversal resonator fitted with a short-circuit duct connecting the inlet and outlet is analysed and used as a tuneable Continue reading
Development of Industrial robots is becoming more expensive and time consuming over the years. A lot of costs are spent in the development, and so it is necessary to Continue reading
The presented study has evaluated the possibility of commercializing a research project at the Royal Institute of Technologys (KTH) Department of Energy Technology (EGI) in Stockholm, Sweden, where a Stirling engine is used for renewable microscale power generation. The purpose of the study has been to Continue reading
Hypersonic vehicles, based on scramjet engines, have the potential to deliver inexpensive access to space when compared with rocket propulsion. The technology, however, is in its infancy and there is still much to be learned from fundamental studies.
Flows that represent the conditions inside a scramjet engine can be generated in ground tests using a free-piston shock tunnel and a combustor model. These facilities provide a convenient location for Continue reading
The objective with this work was to examine the effects of fitness ratio, lift over drag, lift coefficient at cruise, winglet span, wing sweep angle, wing aspect ratio, wing area and weights with respect to Mach number for a conventional business jet capable of Continue reading
With the vastness of existing railroad infrastructure, there exist numerous road crossings which are lacking warning light systems and/or crossing gates due to their remoteness from existing electrical infrastructure. Along with lacking warning light systems, these areas also Continue reading
CubeSat or Cubic Satellite is an effective method to study the space around the Earth thanks to its low cost, easy maintenance and short lead time. However, a great challenge of small satellites lies in achieving Continue reading
The MUSCL-Hancock finite volume method with different slope limiters has been analyzed in the context of a fast transient flow problem. A derivation and analysis of the axial forces inside a pipe system due to a flow transient is also Continue reading
Clap and fling is a particular wing kinematic pattern utilized by some insects and birds to produce enhanced aerodynamic forces. It consists of two very distinct Continue reading
The propagation of waves in rods, shells and rotating shafts with variable thickness is studied through numerical models and experimental measurements. All numerical models are formulated using the Transfer Matrix approach, which accurately reproduces the Continue reading
Two ways in which the concept of open resonator can be used in connection with nondestructive evaluation will be described.
In the first, a noncontact transducer’s efficiency of transferring energy into an object can be increased by Continue reading
