Abstract: Basic governing equations were established to investigate flow and heat transfer characteristics of the thermally driven liquid flow in the enclosure circulation channels in centrifugal force field.From the dimensionless governing equations,the primary similarity criteria,which affect the thermally driven heat transfer were gained.Experiments based on theoretical analysis were carried out to investigate the details of heat transfer of water in centrifugal force field.Through curve fitting of the test data,the similarity criteria for thermally driven heat transfer in centrifugal force field were obtained.
