| Abstract: | The differences of the calculation of thrust forces and the design points between jet fans and common axial-flow fans are presented detailedly in this paper. Procedures to compute total pressure and flow rate of jet fans and key points in designing are discussed. Modeling design equations about jet fans deduced, and advantages of reversible jet fans used in ventilation systems in a tunnel and major changes of jet fan used in high altitude areas are also introduced. |
