Abstract: This paper deals with the technological transformation of the processes of the pulse flow drying system from the point of saving the energy, which can largely reduce the production cost and enhance the competitiveness of products. The authors transformed the secondary separation recovery process into primary separation recovery process, i. e., improved the gas-solid separation part technology of drying system, aiming at the high energy consumption characteristics of potato granules whole meal drying system. Compared to the original process, the improved process can not only use to increase the product output, but also has obvious effect on energy saving. The improved process of low investment and high energy saving has a significant promotional value.

Abstract: A control model for wall thickness thickening of the seamless steel tube end was established to multilevel control the unsteady state rolling process of the tube head and tail ends for the wall thickness thickening problem during the stretch reducing process. The three-dimensional thermal coupling calculation model was established of stretch reducing process on the platform MSC.Marc of nonlinear finite element software to analyze the influences of ends control on the wall thickness distribution of the tube. The cut length of the wall thickness thickening segments of tube head and tail were obtained through analyzing the longitudinal wall thickness distribution of the tube head and tail. The research provides an effective means for improving product quality and reducing the cutting loss.

Abstract: Conceptualisation and subsequent validation are essential for future aerospace vehicle design. In this process, theoretical analysis is often constrained imposed by numerical and physical experimentation limitations. This is where the incorporation of flight and other simulation packages as new tools of real-time investigation, for determining design drivers, estimating flight performance, likely operational scenarios and manufacturing strategies can become so useful. For the past few years, we have been exploring the effectiveness of this new tool at the University of New South Wales. The results appear to be highly promising. In this paper, we outline the various stages of the methodology and demonstrate through a test case how the simulation activity can be implemented in the overall design process. It appears that the incorporation of simulation into the design process has the prospect of ushering in a new era for future advanced project aerospace design that will find application far beyond aerospace industries.

Abstract: Design is about wealth creation for the comfort and well-being of human beings. In this context, the process and experiences associated with teaching and learning of engineering design are pivotal in sustaining and advancing the progress of modern day civilization. However, the teaching of engineering design is not easy and fraught with difficulties as the students have to be provided with the opportunity to develop their creative skills while retaining a professional and practical base. It is also important to proactively harness the available and emerging technologies to greater effect in the learning process. At the University of New South Wales in Australia, we have approached the teaching and learning of design in undergraduate aerospace engineering from a perspective to prepare students to be creative and become practically oriented for productive employment in the very competitive world of today.
