Effect of Whisker Spray on Power of High Speed Planing Hull
Md. Shahidullah Kaiser | Rejaul Karim Shipon | Md. Naimul Hasan
Abstract: Total resistance comprises bare hull resistance, aerodynamic resistance and whisker spray resistance in planing hull. In this thesis, total resistance has been calculated by using C++ computer programming language according to method published by Savitsky in the October 1964. Data have been collected from the paper of Inclusion of Whisker Spray Drag in Performance Prediction method for High Speed Planing Hulls published in January 2007. Empirical formulas have been used as different functions of the code. Giving suitable condition for every functions. Different variables are assigned and makes it ready to be executed. Finally, all the instructions of the program are executed loaded in the memory. Thereof graphs have been generated automatically between Resistance Vs Speed by using Python computer programming language. Afterwards, results are validated with the values taken from the paper of Inclusion of Whisker Spray Drag in Performance Prediction method for High Speed Planing Hulls published in January 2007. After the validation of present program, required power for service planing vessel have been calculated and from which the effect of whisker spray on power of planing hull has been determined.
