Thermodynamic Model of a Hot Air Balloon

  1. Nov 13, 2013 #1
    I need to model the buoyancy of a hot air balloon in Simulink and VRML. I want to the system to be the balloon (simplified to a sphere) with a constant temperature heat source in the center with convection cooling the balloon. The heat source will turn on an off. I need to get the average temperature throughout the balloon, to get the density. Any help on where to start would be helpful. I already have all the buoyancy functions programmed, but I'm rusty on my thermo and am waiting on getting my textbook back from a friend.

    Sorry for not following the template, I don't think it really applied
