Conference Paper
Full-text available
The goal of this study is to introduce a coupling process between a novel meshless scheme for non-Newtonian flows and an arbitrary FEM structural solver. The flow-solving method named Lagrangian Differencing Dynamics (LDD) is based on Lag-rangian differences, volume-conservative advection, and direct interaction with triangu-lated geometry. The flo...

Hydroelastic effects during slamming of high-speed marine vehicles affect the development of the pressure along their bottom. The aim of this study is to investigate coupling process of a novel CFD method and a FEM structural solver for simulation of hydroelastic slamming. As slamming is characterised by violent and strongly nonlinear fluid-structu...

This article discusses numerical prediction of ventilated flows around the surface-piercing hydrofoil. A ventilated cavity is developed on the hydrofoil surface and the growth of the cavity is uncontrolled, which can have harmful effects as it leads to changes in the lift and unexpected loads. The occurrence of ventilation is computed by a Reynolds...

U radu je dat prikaz mogućnosti polifunkcionalnog pučinskog energetskog objekta. Najveće moguće održivo iskorištenje morskog resursa jedan je od odgovora na energetske izazove ali i ostale zahtjeve u nadolazećem vremenu tj. potreba povećanog broja stanovnika na planetu. Morska površina se danas koristi za proizvodnju energije, hrane, vezivanje brod...
Article
Various types of hybrid drives are increasingly being applied in transportation. Wing sails can provide additional propulsion to a motor-driven ship, thereby decreasing fossil fuel consumption. This article contributes to the selection and consideration of the influencing parameters for applying wing sails for ship propulsion. Basic developmental f...

This article focuses on the assessment of the possibility of applying the already existing procedures of CO2 storage and proposal of an acceptable new concept of storage (technical plantation) in accordance with natural resources and socio-economic and technological capabilities. The EU countries aspire to increase the share of renewables in total...
Article
This paper reports and elaborates on the idea of a solar distiller and an offshore wind power plant operating together. The subject under discussion is a single-stage solar distillation plant with vaporization, using adiabatic expansion in the gravitational field inside a wind power plant supporting column. This scheme divides investment costs for...
Article
The article presents application of non destructive testing method based on the pulse heating infrared thermography used to detect material anomalies for the case of glass reinforced polymer structures. The goal of presented research, based on the thermal gradient approach, is to establish the procedure capable of filtering out anomalies from other...
Article
The infrared thermography, together with Thermoelastic Stress Analysis and Pulse heating thermography, is used in evaluation of impact damage in fiberglass composite materials. The controlled impact of fiberglass specimen was recorded by a high frame rate infrared thermal camera. The elastic deformation, together with the damage, was evaluated and...
Conference Paper

Convective vortices can be apprehended as heat engines, because there is similarity between the physical working principles. In both cases the output from the system is in the form of the mechanical work. But question is how large is the magnitude of the mechanical work in the case of convective vortices utilization? Concept of mechanical work prod...
Article
This research is based on both, theoretical and experimental work and aims to assessment the yield point of concrete steels, based on the known alloy chemical composition. The experimental portion of the work was performed at the Split steelmaking factory, which produces concrete steels from the waste iron. The theoretical portion of this study inv...

In this paper, a simplified analytical approach for evaluating the factor of turbine pressure drop in solar chimney power plants is presented. This characteristic factor (or pressure drop ratio in turbines, according to the total pressure drop in the chimney) is important because it is related to the output power. The determined factor (or ratio) v...

This paper deals with the simulation results and investigation procedure on adaptive airfoils applied to wind turbines. A flexible airfoil skin is attached to the stiff airfoil core and allows deformation of the geometry due to pressure field change. The leading edge of the airfoil is made as a flexible structure and attached to the blade element....

The biggest fire fighting accident in the history of Croatia happened on August 30, 2007. The routine fire fighting operation ended with 12 dead and one badly injured firefighter. That was the biggest human loss in the history of fire fighting in Croatia. In order to understand the Kornati accident, a research team was formed and an independent sci...

This paper deals with the investigation procedure and results of applying an adaptive airfoil for wind turbine blades. A flexible airfoil skin allows deformation in the elastic zone of the adaptive part of the airfoil. This skin is attached on the stiff airfoil core. The deformation of the flexible airfoil shape depends on forces caused by the pres...
