Using non-othogonal body-fitting grid system  with control-volume finite difference method, the  interface shape can be detrmined both efficiency and  accurately. During stable growth, the dependence of  the MZ length and shape on the heating CO2 laser is  examined in detail under boh the maximum and the  minimum allowed powers with various growth speeds.      After comparing with the MZ shape in terms of  the experiment and simulation, heat transfer and  fluid flow in LHPG system are analyzed near the  deformed interfaces. The global thermal  distributions are decribed by temperature and its  axial gradient within model length of ~10 mm. As  compared with the growth of bulk crystal of several  centimeters in dimension, natural convection drops  six orders in magnitude due to smaller melt volume;  therefore, conduction rather than convection  determines the temperature distribution in the MZ.  Moreover, thermocapillary convection rather than  mass-transfer convection becomes dominant.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838332796\"\u003e\u003ch3\u003eSimulation model and the analysis of interface shape, heat transferm and fluid flow\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838332796","offer_id":39498988617821,"sku":"9783838332796","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/23876f22-9130-4a0f-b741-c33314aa85fa.jpg?v=1757743577","url":"https:\/\/shop.autorenwelt.de\/products\/crystal-fiber-growth-using-laser-heated-pedestal-growth-method-von-peng-yi-chen-chun-lin-chang-und-sheng-lung-huang","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
