The research institution conducted computational studies of wind impacts on a high-rise building with an integrated wind power plant developed under the W.E.T.E.R project
Active work is underway on the development and implementation of the W.E.T.E.R project, which provides for the development of a new technical solution for generating electricity using wind - a wind energy complex. This technically complex facility, consisting of a building with an integrated vertical-axis wind power plant, requires extensive research and calculations to obtain the necessary design solutions.

In order to study wind impacts on a building with a height of 156 meters with an integrated wind power plant, in December 2023, a paid contract was concluded between WETER LLC (Customer) and a National Research University (Contractor) to perform research work with the provision of a report on the results of research and calculations.
To carry out the research, the Contractor requested data: design documentation in electronic form for the complex under study; a solid-state three-dimensional CAD model of the object under study; a line plan of the adjacent territory in electronic form with information on the elevation difference and level of buildings and structures (the proposed construction area is the city of Dubai, UAE).
In February 2024, a scientific and technical report was received from the NRU, provided for in the contract for the provision of research services, which reflects:
- methodology and methods of calculating the surface of the object under study and wind loads;
- recommendations for determining the wind load to justify the mechanical safety of the facility;
During the research, the analysis of meteorological and topographic data in the development area took place. The Contractor modeled the wind structure in Dubai. Studies and subsequent calculation of dimensionless values of aerodynamic coefficients and corresponding values of wind load on the building were carried out.
The Contractor performed a numerical simulation of the wind impact on the object under study based on its constructed geometry, during which the calculation was performed:
- distribution of the average aerodynamic coefficient along the facade of the object under study;
- distribution of peak values of the aerodynamic coefficient along the facades of the object under study.
Based on the analysis of the results of computational and experimental modeling, the most unfavorable (critical) directions of the wind flow, the normative values of the average component of the main and peak wind load on the studied object are determined. The obtained indicators allow us to independently determine the wind load on the facades of the object under study, setting our own values of the standard wind pressure and reliability coefficient in accordance with the requirements for the construction object.
The research of the facility (wind energy complex) took place in two main stages:
1. Computational studies in a specialized software package of fluid and gas dynamics.
At this stage, a three-dimensional computer model of the object under study has been created, a series of calculations have been carried out in order to preliminarily assess the average component of the main and peak wind load on the surface, enclosing structures of the object under study.
2. Experimental modeling of wind effects on the physical model of an object in a wind tunnel.
At this stage, a physical model of the object under study was created on a reduced scale, a series of tests were carried out in a wind tunnel of the architectural and construction type of the object in order to determine the average and peak wind load on the object under study, as well as verification of the results of computational studies, their refinement and correction.
Conducting such studies is necessary for the design, determination of materials and structures to be used in the construction of a wind energy complex. The result of complex research is the numerical values (indicators) of the wind load necessary for the calculation of the main load-bearing structures and enclosing structures (facade surfaces) of the object under study.
The W.E.T.E.R project team will use the obtained research results for further work on the calculation and design of the main load-bearing structures and enclosing structures (facade surfaces) of the facility - a high-rise building with an integrated wind energy complex applied to the territory of Dubai, where the construction of the first wind energy building is projected.
The difficult work on the implementation of the project and the construction of the wind energy complex continues.
