While the articles are often interesting, because of the brevity, incompleteness, and complexities, it is not clear how to practically use the information. For the application to ships, these drag reduction methods could lead to significant fuel savings. Figure 2 shows the percentage change in drag Eq. By Volker Nolte. The Short and Snarky.

Polymer concentrations have a continuous downstream decrease, and it thus demands complex injection apparatus to maintain the drag reducing abilities over a significant downstream distance [4]. Air bubbles or films shows similar practical problems. Due to coalescence or break up of air bubbles and films, it is difficult to maintain a constant and stable drag reducing performance [6].

A promising solution to reduce drag and to avoid complex injection methods is the use of specific drag reducing coatings.

Much research has been dedicated to superhydrophobic and superhydrophilic surfaces [6,7], which are micron-scaled rough surfaces with a hydrophobic or hydrophilic character and which are inspired by surfaces in nature. Pearl-shaped water droplets are formed on a superhydrophobic surfaces, like droplets on a Lotus leaf. These droplets have contact angles up to o for superhydrophobic surfaces and o for superhydrophilic surfaces [8].

Significant darg reduction is shown in external flow experiments by Balasubramanian et al. Riblets are small surface protrusions that are aligned in the flow direction [9]. They reduce drag by impeding the spanwise motion of the flow at the surface, and thereby moving turbulent vortices further away from the wall. The focus of the present study is to develop, characterize and test specific surfaces that can reduce the turbulent drag of water sport objects, such as rowing boats, sailing boats, kayaks, surfboards, and swimsuits.

The first part of this research concerned the development and investigation of a testing facility, which is a Taylor-Couette system. Turbulent Taylor-Couette flow is the fluid motion between two co- axial cylinders, having characteristics very similar to a turbulent boundary layer as, for example, a rowing boat [12].

The second part consists of testing and studying several commercially available products that claim to provide drag reduction. In the future, self-developed surfaces will be characterized and tested on their drag reducing effect in the Taylor-Couette facility lab and in actual field tests practice with rowing and sailing boats. Arnoud Greidanus et al. Taylor-Couette systems are very useful for drag reduction studies of surfactants, microbubbles, riblets and highly water-repellent walls [].

The Taylor-Couette facility Fig. The system is closed at both ends where the top and bottom end-plates are rotating with the outer cylinder. The total torque TTot is measured on the inner cylinder by a co-rotating torque meter on the inner cylinder shaft.

For the current study the Taylor-Couette system was filled with water.

For perfect counter-rotation, Eq. The counter-rotation was gradually increased up to a shear Reynolds number Res of 1. The range of velocities and gap width correspond to typical velocities and boundary layer thickness, respectively, encountered in the water sports mentioned previously. Results 4. Facility validation by riblet drag measurements. In order to confirm the magnitude of drag reduction in the Taylor-Couette facility, riblet foil was attached on the inner cylinder surface.

Figure 2 shows the percentage change in drag Eq. It indicates how far the riblets protrude from the surface into the turbulent boundary layer. Riblets trend solid black line found by Hall [15] Figure 2 indicates a similar trend as was found in experiments reported by Hall [15]. This can be solved by replacing water by a more viscous working fluid and will be carried out in the coming months. The overall data shows that the Taylor-Couette facility is capable of predicting qualitative and quantitative drag reduction measurements.

This book is a collection of about thirty articles covering many aspects of rowing at an elite level written by scientists, coaches, and athletes most of whom are now coaches with vast experience and accomplishments in rowing. While good to elite rowers will find some of the articles interesting, the book is geared towards coaches wanting to get the most out of their athletes.

Some of the topics are coaching philosophy, long-term athlete development, understanding how athletes learn, rowing physiology and biomechanics, strength training, nutrition, the psychology of rowing, how to select athletes, racing and tapering for races, boat setup, and the future of rowing.

Almost all of the articles evidence some or all of the following shortcomings: While the articles are often interesting, because of the brevity, incompleteness, and complexities, it is not clear how to practically use the information. It is doubtful that a good rower could take this book and put him- or herself on a path to being a faster rower.

Loves the sport and is now rowing at the collegiate level. I thought this would give him some pointers to help his team move faster through the water.

He likes the book so far. Superb footnoted scientific review of all aspects of rowing. Very useful for coaches and high performance athletes. One person found this helpful.

Well developed ideas things to consider to improve boat speed. Read it once clover to cover. Then leave it handy and refer to it now and then. You will enjoy it. Kindle Edition Verified Purchase. Really informative with specific information such as physiology and weights training.

Have to seperate some of the information which isn't really relevant to me, but well set out to make it easier to do so.
