Air flowrates varying from 0.45-10 g\/s were used with fuel flowrates set at the appropriate stoichiometric values. Intake port temperatures were held at values ranging from 30-120\u00b0C and inlet valve temperatures at values from 50-300\u00b0C. At temperatures up to approximately 80\u00b0C surfaces were wetted with fuel and heat transfer was mainly convective. Above 80\u00b0C nucleate boiling set in and dry patches began to form. Above 230\u00b0C film boiling occurred and heat transfer became very unstable.<\/div><\/jats:p>","DOI":"10.4271\/900583","type":"proceedings-article","created":{"date-parts":[[2010,10,15]],"date-time":"2010-10-15T16:07:24Z","timestamp":1287158844000},"source":"Crossref","is-referenced-by-count":9,"title":["Heat Transfer to Air-Ethanol and Air-Methanol Sprays Flowing in Heated Ducts and Across Heated Intake Valves"],"prefix":"10.4271","volume":"1","author":[{"given":"J J G","family":"Martins","sequence":"first","affiliation":[]},{"given":"I C","family":"Finlay","sequence":"additional","affiliation":[]}],"member":"2796","published-online":{"date-parts":[[1990,2,1]]},"reference":[{"key":"ref0","unstructured":"BROWNING, L.
