Abstract

Filtering of experimental data at arbitrarily located points of planes and surfaces S. Lukasiewicz*, M. Stanuszek^, R. Qian% M. KajV * Department of Mechanical Engineering, The University of Calgary, Alberta, Canada. ~ Institute for Numerical Computations, Krakow Technical University, Poland. Abstract The paper presents generalization of the method previously developed for regular meshes for filtering of the experimental or numerical data [1, 2]. The data obtained from measurements or numerical analysis of various technical problems always contain some errors caused by inaccuracies of measuring techniques and instruments and also due to some imperfections of the numerical methods. The generalization presented here makes it possible to use the filtering technique in the cases when the data is collected at arbitrary points of surfaces, or time, and is not necessarily located on regular rectangular meshes. The obtained data is usually collected at arbitrarily located points
