The turbine model was scaled down by 1/10 to acquire detailed flow field information. The experimental study was to measure instantaneous velocity fields near the field of the blade using a 2D PIV method ( Particle Image Velocimetry). The turbine is designed to produce energy by both lift and drag forces on the blade but it mainly depends on the drag force. This is done by carrying numerical and experimental studies. The study goal is to investigate the aerodynamic characteristics of an Archimedes spiral wind turbine for urban usage. One of the key features of this turbine is that can start rotating at low wind speed as demonstrated in this video of the field test (Low Wind Speed) It consists of 3 blades three-dimensional conical shape.

The Archimedes spiral wind turbine is a type of horizontal axis wind turbine HAWTs but unlike traditional HAWT that uses lift force generated by air pushed down by an Aerodynamic shape ( Airfoil), This turbine uses drag force to harness the energy from the wind. In this article, we will summarize one of them. Many Research papers were published as a result of collaboration between Esco RTS, Pusan National University. The AWM is tested in almost every weather condition.” As mentioned in the history article on the company website. Among the tests were many performance wind tunnel tests, wind force tests up to 50 m/s, and many field tests in South Korea, The Netherlands, Germany, Spain, Poland, Czech, Dutch Antilles, and India. Tests and development all took place in Korea, together with Esco RTS, the Pusan National University, Borim, and other Korean partners. “In 2012 MSc Marinus Mieremet moved to South Korea and started working together with the Korean company Esco RTS.

The key characteristic of the AWM is that harnesses more energy, produces low noise, bird-friendly, and looks very pleasant.
