Sun, Y. (author), Xiong, L. (author), Su, P. (author)In sports facilities, a grandstand is the structure which provides good sight quality and safety evacuation conditions for the spectators. Grandstand plays important functional and formative roles in sports facilities, and especially in large scale stadia. This paper argues the notion of shape grammar and its computer implementation will solve...conference paper 2013

Thipyopas, C. (author), Sun, A.B. (author), Bernard, E. (author), Moschetta, J.-M. (author)A new Nano Air Vehicle (NAV) configuration based on a coaxial nano rotor has been studied by ISAE. The coaxial rotor provides the thrust necessary for hovering and low speed translation flight. The major design challenge for rotary-wing NAVs is related to the difficulty of miniaturizing complex mechanisms such as a rotor cyclic pitch swashplate...conference paper 2011

We investigate the double diffusive convection between two parallel plates with either no-slip or free-slip boundary conditions. Direct numerical simulations have been conducted systematically for a series of control parameters. Salt fingers can be observed for both boundary conditions and all parameters explored. Compared to the no-slip case,...conference paper 2015

Sun, Z. (author), Van Oudheusden, B.W. (author), Schrijer, F.F.J. (author), Scarano, F. (author)The wake resulting from two micro ramps operating in a supersonic boundary layer at Ma = 2:0 is investigated by means of PIV. Two micro ramps are investigated with height of 60% and 80% of the undisturbed boundary layer with thickness of 5.2 mm. The measurement domain encompasses the range from 10 to 32 ramp heights downstream of the device. The...conference paper 2013

Sun, Jing (author), Paasch, Jesper M. (author), Paulsson, Jenny (author), Tarandi, Väino (author), Harrie, Lars (author)With the increased interest and demand for 3D property, 3D property formation has shown increased significance. It is important to provide efficient, clear and unambiguous methods to form 3D property units, as well as register 3D property RRRs (rights, restrictions and responsibilities). The 3D property formation process should facilitate...conference paper 2021

Dalmau, Ramon (author), Sun, Junzi (author), Prats, Xavier (author)The vertical trajectory plan (altitude and speed) corresponding to the descent phase of a modern airliner is computed by the on-board flight management system while the aircraft is still in cruise. As long as the constraints on the arrival procedure allow, this system plans for an idle descent and the exact location of the (optimal) top of...conference paper 2021

Sun, Junzi (author), Marinescu, M. (author), Olivares, Alberto (author), Staffetti, Ernesto (author)Accurate wind information is crucial in air traffic management, for instance, to improve trajectory predictability and precision in controlled time of arrival. Nowadays, air traffic management relies on Numerical Weather Prediction, which usually has a low resolution and low update rate. A potential approach for improving the resolution and...conference paper 2021

Bonifazi, A. (author), Sun, Junzi (author), van Baren, Gerben (author), Hoekstra, J.M. (author)Not all flight data anomalies correspond to operational safety concerns. But anomalous safety events can be linked to anomalies in flight data. During the final phases of a flight, two significant safety events are unstable approach and goaround. In this paper, using Automatic Dependent Surveillance- Broadcast (ADS-B) data, we develop several...conference paper 2021

Sun, Yubo (author), Chen, B. (author), Zhang, Shizhe (author), Blom, Kees (author), Lukovic, M. (author), Ye, G. (author)In recent years, the rapid industrialization and urbanization led to the explosive growth of municipal solid waste incineration (MSWI) bottom ashes (BA) production. However, most of them are directly landfilled, which not only brings environmental burden but also results in loss of potential resources. Present researches have proved that MSWI BA...conference paper 2021
