Scientific Methodology Directing the Research Subject Selection of PH.D Dissertation

The research subject selection of PH.D dissertation was very important.The grim situation of oil resources shortage in the world today and the policy of energy saving and emissions reduction were introduced.And the key problem of energy saving was to enhanced heat transfer and reduced energy consumption of air-condition.Using the basal universal relation principium of dialectic materialism,the computational fluid dynamics method and experiment technology was used to investigate the air flow and heat transfer in a cross-corrugated triangular duct.Applying the basal principiums of dialectic materialism and scientific methodology,the background,the research object,the research contents,the key problems to be solved and the significance of dissertation were disccused from the necessary principle,innovation principle,scientific principle and feasible principle of scientific research selection.
