Modeling of an isolated liquid hydrogen droplet evaporation and combustion

•Diffusive governing equations of Liquid Hydrogen (LH) evaporation and combustion were solved.•There exists a critical radius (acri) where radiation heat is equal to conduction heat (Qrad = Qcond)•Radiation heat is dominant at a given environment temperature for large liquid hydrogen droplets (a > acri).•The flame profiles including flame temperature and location were simulated under differ combustion conditions.
