Effects of inclined impermeable bed on the turbulent characteristics of the flow using particle image velocimetry
Keramaris, E. (2015)In this study, the turbulent characteristics of the flow in an open channel with horizontal and inclined impermeable beds were studied experimentally using two-dimensional particle image velocimetry (PIV). The experiments ... -
ENERGY PRODUCTION FROM SEA WAVES AND CURRENTS. A GENERAL REVIEW
Savvidis, Y. G.; Zafiriou, S. V.; Keramaris, E. (2013)Energy from the sea constitutes the 'blue' type of the renewable energy sources (RES). During the last decades, a number of devices for electric energy production from sea waves and currents are in implementation. Depending ... -
Experimental study of the effects of grass vegetation and gravel bed on the turbulent flow using particle image velocimetry
Pechlivanidis, G.; Keramaris, E.; Pechlivanidis, I. (2015)Laboratory experiments are used to explore the effect of impermeable bed on the turbulent flow by using particle image velocimetry (PIV). The experiments were conducted in an open channel of 6.5 m length, 7.5 cm width and ... -
Shear stress estimation in the linear zone over impermeable and permeable beds in open channels
Pechlivanidis, G. I.; Keramaris, E.; Pechlivanidis, I. G.; Samaras, G. A. (2015)This paper investigates the shear stresses in the linear zone of open channel flows with permeable and impermeable bed. The permeable bed is simulated using a flexible vegetation of 2 cm thickness. Laboratory experiments ... -
Transition from permeable to impermeable beds and vice versa in open channels: Effects on the velocity distribution of turbulent flow
Pechlivanidis, G.; Keramaris, E.; Pechlivanidis, I. (2014)This study investigates the impact of permeable to impermeable (and vice versa) bed transition on the velocity distribution of turbulent flow in an open channel. This experimental investigation is based on the 2D Particle ...
