Energy efficiency gains through modelling and site measurements for Nazarbayev University Technopark

The paper will present the strategies to minimise energy consumption of Technopark, which is a building located near the Main building of Nazarbayev University. It incorporates space for laboratories, offices and prototyping centre. Its annual energy consumption will be modelled using the software package BIM HVAC, based on the operation of building as well as taking into consideration of all the installed civil, mechanical and electrical systems. For the mechanical and electrical systems, equipment ratings and actual energy consumption will be collected and examined. The simulation data will then be compared with measured consumption. Various methods of energy minimisation, which will be mainly focused on modifying the operations of the system and, to a lesser extent physical modification of the system, will be modelled and suggested

HIGH-FIDELITY 2-WAY FSI SIMULATION OF AWIND TURBINE USING FULLY STRUCTURED MULTIBLOCK MESHES IN OPENFOAM FOR ACCURATE AERO-ELASTIC ANALYSIS

With increased interest in renewable energy, the power capacity of wind turbines is constantly increasing, which leads to increased rotor sizes. With ever larger rotor diameters, the complex and non-linear fluid-structure interaction (FSI) effects on wind turbine aerodynamic performances become significant, which can be fully studied using hi-fidelity 2-way FSI simulation. In this study, a two-way FSI model is developed and implemented in Openfoam to investigate the FSI effects on the NREL Phase VI wind turbine. The fully structured multiblock (MB) mesh method is used for the fluid and solid domains to achieve good accuracy. A coupling method based on the ALE is developed to ensure rotation and deformation can happen simultaneously and smoothly. The simulation results show that hi-fidelity CFD (Computational Fluid Dynamics) and CSD (Computational Structural Dynamics) -based 2-way FSI simulation provides high accurate results for wind turbine simulation and multi-disciplinary design optimization (MDO)
