The growing demand for electricity in developing countries is a source of concern and therefore it is necessary to explore other methods of energy generation in which one of the methods is considered in this study. The power generation is through a bladeless turbine that operates on incompressible fluid and has a renewable energy source that is available throughout the year. The flow model (Laminar flow) is linearized for experimental design and construction of a prototype bladeless turbine with an incompressible air medium and inclusion of air moisture regulator (ATR). The introduced ATR device is connected to the air hose that linked up with the inlet nozzle to filter the airflow moisture and it has a strong influence and yielded better performance on the turbine output. The findings are presented graphically and discussed for the bladeless turbine performance to portray the impacts of the important embodiment parameters. The experimental bladeless turbine Reynold’s number Re ​≤ ​528.53 and rotational speed ≤944.31 ​rad/s operating within the laminar range of efficiency 23.9% while model efficiency is 34%. The efficiency comparison of the analytical solutions model to the experimental (prototype) bladeless turbine revealed a notable divergence, but the correlation between calculated theoretical results and the experimental (prototype) results are significant. The comparison, correlations amid performance parameters with the introduced ATR device connected to the air hose that linked up with the inlet nozzle to filter the airflow moisture are examined in the experiments and the results are analyzed using Graphpad 5.0 computer software.
