In this work, by numerical simulation using a commercial CFD (computational fluids dynamics) code, were obtained the velocity fields and thermal fields, inside of an indirect type natural convection solar food-dryer. For validating the numerical simulation, was developed an experimental model of an indirect type natural convection solar food-dryer. The food-dryer was instrumented with thermocouples...
This paper discusses techniques to develop the database of civil aviation Air Traffic Control (ATC) Tower scene database and optimize approaches of 3D model by virtue of the professional modeling tool -MultiGen Creator. The ATC Tower visual simulation system is established combined with Vega Prime. However, excessive amount of data make the system not run smoothly, thus, a number of the corresponding...
Engine room of a ship is an environment scattered numbers of components. Pipe-routing arrangement should meet various requirement or constraints referring to either properties of individual components or relationships between components. The models of environment and components must be simplified by appropriate method to ensure an accurate and effectual design. An approach was proposed to construct...
In this paper the scope and type of models and simulations used in defence system acquisition are reviewed. The principles of Simulation-Based Defence Acquisition are presented and discussed in the context of the changes and challenges of complex systems acquisition management. The paper also presents different case studies that illustrate to what extent modelling and simulation were used in major...
