In this paper we report on the results of the Blind Test 2 workshop, organized by Norcowe and Nowitech in Trondheim, Norway in October 2012. This workshop was arranged in order to find out how well wind turbine simulation models perform when applied to two turbines operating in line. Modelers...

For application of kites to ships for power and propulsion, a scheme for predicting time averaged kite forces is required. This paper presents a method for parameterizing figure of eight shape kite trajectories and for predicting kite velocity, force and other performance characteristics....

The regenerator is one of the essential components in a liquid desiccant air-conditioning system, whose efficiency directly influences the system performance. A performance test-bed for a cross-flow regenerator was established in the present analysis. Celdek structured packings were used in the...

A mathematical model which was developed to predict steady state performance of a biomass downdraft gasifier/spark ignition engine power system is described. A mathematical model of the integrated system consists of two parts: the fixed bed downdraft gasifier and spark ignition internal...

Dehumidifier is the core component in a liquid desiccant air-conditioning system, whose efficiency directly affects the whole performance. In this study a cross-flow dehumidifier was established in which LiCl solution and Celdek structured packing were used. Enthalpy efficiency and moisture...

Low head Pico hydro resources have considerable potentials in many regions of the world and with increasing demand of energy, use of such capacities is quite necessary. Pico hydro plants are usually isolated and installed in remote areas. One of the main problems of utilizing these potentials...

The ambient turbulence intensity in the upstream flow plays a decisive role in the behaviour of horizontal axis marine current turbines.

This paper proposes a snow storage system in a renovated space for efficient energy use and reduction of the costs related to snow utilization, and aims to clarify the system’s effectiveness. First, it gives an outline of the system together with a description of the facility used for...

Among the various ocean energy resources in Korea, the tidal currents in the South western sea have a large potential for development tidal current power generation. The biggest advantage of tidal power is that it is not dependent on seasons or weather and is always constant. This makes power...
