VTOL Unmanned Aerial Helicopters – A Concept Study
ABSTRACT
This study deals with the development of a Conceptual Design Tool for unmanned helicopters, so called VTOL UAVs. The goal of the Design Continue reading
Simulating Fluid Flow and Heat Transfer Using Dissipative Particle Dynamics
Dissipative particle dynamics is a relatively new technique for simulating fluid flow at meso scales that is more computationally efficient but at the same time able to Continue reading
Estimating of Work Hardening in Bent Sheet Metal Products at an Early Stage of Virtual Product Development
The thesis has two aims: firstly, to investigate the influence of work hardening due to forming simulation on test simulation. The investigated question was also: Is it worth the effort to include work hardening effect into Continue reading
Simulation of Plume-Spacecraft Interaction
When the plume of a thruster impinges on spacecraft surfaces and instruments, the ow is either in the transitional or the free-molecular regime. The standard method to simulate the transitional regime is Direct Simulation Monte-Carlo, which Continue reading
Novel Defrost Techniques on Air Source Heat Pumps
This study aimed to reach a new solution for the defrost problem for air source heat pumps. In order to achieve this goal, the study was divided in 3 different parts. A literature survey about what the Continue reading
Simplified Finite Element Bearing Modeling: With NX Nastran
When conducting finite element analysis on the robots the accuracy of the component modelling and definitions of the boundary conditions becomes more important. One such component is the ball bearing which Continue reading
Numerical Simulation in Automotive Design
Focussing on those areas of simulation which dominate the large-scale computational requirements within the automotive industry, the initial aim of the paper is to give an insight into typical applications and algorithms being used. Beyond this, the main emphasis will be on the more Continue reading
Simulation in the Automobile Industry
