APPLICATION OF B-SPLINES METHOD FOR INTERPOLATION OF THERMODYNAMIC FUNCTIONS OF SATURATED STEAM AND WATER

The application of spline function for interpolation of one variable thermodynamic functions, is presented, theoretical basis of B-splines interpolation, thé method of determination of the knot values and its practical application are described. The computer code based on that method has been verified. Accuracy, smoothness and quick-running make the package veryuseful.
