Dinchev Posted October 11, 2019 Report Share Posted October 11, 2019 Hello, When we use a fan as a jet fan or Jetfan, its performance (trust) or (induced pressure) also depends on the density of the air. However, after the change in air density, productivity does not change, only the speed factor. Please check (trust) changes from air density changes.

Martin Griffith Posted October 16, 2019 Report Share Posted October 16, 2019 Hi Dinchev, Thank you for your message and for bringing this to our attention. When specifying a fan or a jet fan, the user needs to set a density on the fan, which is the density at which the fan curve or the thrust of the jet fan is specified. For jet fans and for fans being used as jet fans, the correction for this fan density to the density in the airway has not been done. We're going to correct this bug for the next Ventsim patch release, which should be out soon. I'll post here again once the new version is up on our website. Thanks again, Martin Quote Link to comment Share on other sites More sharing options...
