Salt-water simulation experiment research of stack-based hybrid ventilation for multi-story buildings

Examines the feasibility of the stack-based hybrid ventilation theory by means of the salt-water model experiment. Presents a stack-based hybrid ventilation scheme for multi-story buildings and the quantitative design method. Expounds the principle of the salt-water experiment, similarity rate and the methods of parameter selection, and studies the similarity criterion of salt-water experiment. Taking a scale-down (1∶40) three-layer building as the experimental object, carries out the salt-water experiments under three different conditions. The results show that the stack-based hybrid ventilation is a kind of feasible scheme for multistory buildings.
