The design and aerodynamic characteristics of an 18% thick shock-free airfoil (NLR 7501)

The design and experimental verification of a thick (18 %), shock free airfoil is described. The design was performed, using the NLR hodograph theory for transonic airfoil design. The airfoil was experimentally investigated in the NLR Pilot tunnel.

Low cost rock structures for beach control and coast protection: Practical design guidance SR 631

Coastal rock structures are widely used in coastal engineering for a variety o f purposes, includiag controlling the morphological development of beaches and providing protection against coastal erosion or flooding by wave overtopping. Strict adherence to existing design guidance has resulted in many of these structures being built using...

The calculation of aerodynamic characteristics of wing-body combinations at subsonic flight speeds

Surface panel methods and finite difference methods are reviewed with respect to the use in the design of aeroplanes. It is concluded that there is a need for inverse surface panel type methods to diminish the trial and error character of the design process. Finite difference methods based on transonic small perturbation theory have to be based...

Confronting Informality: Preserving communities and creating public goods in informal settlements

The Confronting Informality Symposium is a student-led event sponsored by the Chair of Spatial Planning & Strategy at the Department of Urbanism, TU Delft University of Technology. The symposium happens once a year and gathers experts, policy-makers, practitioners and others to discuss informal urbanisation, its political, economic and...

Design of Microbial Methane Oxidation Systems for Landfills

Landfill methane currently represents the largest global source of greenhouse gas emissions from the solid waste sector. Emissions are expected to increase due to increasing waste generation, particularly in countries still landfilling biodegradable wastes. As a complementary measure to gas extraction with subsequent flaring or energy conversion...

Monitoring the Well-being of Older People by Energy Usage Patterns: Systematic Review of the Literature and Evidence Synthesis

Background: Due to the aging population, there is a need for monitoring well-being and safety while living independently. A low-intrusive monitoring system is based on a person’s use of energy or water. Objective: The study's objective was to provide a systematic overview of studies that monitor the health and well-being of older people using...
