Abstract: The influence of temperature on cross-hatching on cone models made of wax and camphor is studied. Ablating experiments are carried out in heated supersonic tunnels. The relation between temperature and the wavelength of hatching is obtained. The relation between pressure and the wavelength of hatching is verified. The influence of temperature and pressure on the initial position of the appearance of hatching and on the time required for both the appearance of hatching and the formation of stable hatching an...
