As computer models become more reliable and able to represent more realistic problems, detailed data is leading to the development of appropriate new types of experiments. Experimental measurements are conditioned to the requirements of the computational models. Hence it is important that scientists working on experiments communicate with researchers developing computer codes, as well as those carrying out measurements on prototypes. The orderly and progressive concurrent development of all these fields is essential for the progress of engineering sciences. CMEM 2009 is the Fourteenth International Conference in this well established series on Computational Methods and Experimental Measurements. These successful meetings provide a unique forum for the review of the latest work on the interaction between computational methods and experimental measurements. The topics include: Computational and Experimental Methods; Experimental and Computational Analysis; Direct, Indirect and In-Situ Measurements; Detection and Signal Processing; Data Processing; Fluid Flow; Heat Transfer and Thermal Processes; Material Characterisation; Structural and Stress Analysis; Industrial Applications; Forest Fires.
