RÉSUMÉ

On a small-scale setup, we carried out investigations of the process of interaction of a heated solid hemispherical surface with water. We studied the processes of the development of instability and rupture of a vapor layer. As a measuring system we used fiber-optical transducers of pressure and of vapor-film thickness. Video filming of the process of the destabilization and rupture of a vapor film was made with subsequent computer processing of pictures.
