  Influence of Emissivity on Airframe Surface Temperature Under Transient Thermal Conditions: A Finite Element Analysis Using ANSYS APDL
  Author(s): Muri Venkateswara Karthik*
  
  This study explores the influence of emissivity on the surface temperature of airframes under transient thermal conditions, employing ANSYS APDL for simulation. The research is driven by the critical need for effective thermal management in airframes, which are essential structural components in aerospace and automotive industries. The analysis was conducted on a hollow steel airframe with an external diameter of 250 mm, an internal diameter of 248 mm, and a length of 300 mm. The model was discretized using solid-8 node 70 element, with a mesh size of 1 mm. A constant heat flux of 10,000 W/m2 was applied to the airframe’s wall over a period of 300 seconds, with a time step of 1 second, to simulate the heat transfer conditions. The study systematically varied the emissivity from 0.05 to 1, in increments of 0.05, to assess its impact on the airframe's surface temperature. Resu.. Read More»
