INTRODUCTION

The articles [1], [3] and [5] have analysed the tests of a free-flow hydraulic turbine of an original design and also have substantiated and analysed a special hydrodynamic effect that appears in a free-flow stream of liquid, which is believed to be a reason for the fairly high specific power output of the above device.
