Model-Based Impact Analysis of Vehicle-Integrated Photovoltaics and Vehicle-to-Grid on Electric Vehicle Battery Life

Electric vehicles (EVs) equipped with vehicle-integrated photovoltaics (VIPV) and EVs with vehicle-to-grid (V2G) technology can support in overcoming power grid challenges emerging from the energy transition. Despite the widespread benefits that VIPV and V2G have to offer, their potential impact on battery life governs their economic viability....

Computational prediction of underwater radiated noise of cavitating marine propellers: On the accuracy of semi-empirical models

The potential impact of underwater radiated noise from maritime operations on marine fauna has become an important issue. The most dominant noise source on a propeller-driven vessel is propeller cavitation, producing both structure-borne and radiated noise, with a broad spectrum that covers a wide range of frequencies. To ensure acceptable...

Improving Capabilities in Modeling Aircraft Noise Sources

Today's globalized world depends on civil air transportation, which has been continuously growing over the last decades. Nevertheless, the sustainability of this expansion is a challenge due to environmental problems. Along with greenhouse gas emissions, noise represents a severe hazard for human health, and consequently, noise regulations limit...

Cockpit Design and Integration into the Flying V

The Flying V is an innovative new aircraft concept currently being developed by the faculty of Aerospace Engineering at Delft University of Technology. This aircraft is a flying wing having a large sweep on the inner section, and a small sweep angle at the outer, giving the aircraft its characteristic V shape. The objective of this research is...

Experimental and theoretical investigation of crack width calculation methods for RC ties

This paper theoretically and experimentally investigates the semi-empirical formulas recommended by Eurocode 2 (EC2), fib Model Code 2010 (MC2010), and Eurocode 2 with the German National Annex (DIN) for calculating crack widths in reinforced concrete. It is shown that the formulas can be derived from the principles for the idealized behavior...

An ALGOL-program for the calculation of incompressible three-dimensional turbulent boundary layers

A computer program has been prepared for the calculation of turbulent boundary layer development, based on a 3-D version of the turbulent energy method. The method is briefly discussed. The computer program is described in detail. The present program is restricted to developable surfaces.

A model for the calculation of the properties of a jet in a three dimensional non-uniform main flow

A model is derived for the calculation of the properties of a jet exhausting into a non-uniform main flow, at an arbitrary angle to the initial jet direction. The model is a generalisation of an earlier jet-ina-main flow model for uniform main flows. Semi empirical input is limited to an entrainment relation and a relation for form factors of...
