Heat Transfer topics are commonly of a very complex nature. Often different mechanisms like heat conduction, convection, thermal radiation, and non-linear phenomena, such as temperature-dependent thermophysical properties, and phase changes occur simultaneously. New developments in numerical solution methods of partial differential equations and access to high-speed, efficient and cheap computers have led to dramatic advances during recent years. This book contains the edited versions of the papers presented at the Ninth International Conference on Advanced Computational Methods and Experimental Measurements in Heat Transfer and Mass Transfer. The objective of this conference series is to provide a forum for presentation and discussion of advanced topics, new approaches and application of advanced computational methods and experimental measurements to heat and mass transfer problems. The selected sections show the wide range of applied and fundamental problems in the heat and mass transfer field. Papers encompass a number of topics such as: Natural and forced convection; Advances in computational methods; Heat and mass transfer; Modelling and experiments; Heat exchangers and equipment; Energy systems; Micro and nano scale heat and mass transfer.
