“…Overall, the ascent rate gradually increase until the balloon nears its float altitude which occurs after approximately 170 min. This qualitatively agrees with the dynamic model in Zhang and Liu (2015) which assumes constant C D . The relatively large variation of ascent rates below 3000 m may be due to meteorological conditions in the mixing layer as well as changes in the drag coefficient C D which depends on shape and Reynolds number.…”

“…Reference [8] established the thermal analysis for flying bodies owing to its significant effect. Reference [9] presented the numerical and dynamical models describing the thermodynamic characteristics for high altitude balloons. Inflation quantity was considered a significant factor that affected on balloon ascending speed and differential pressure.…”
