Abstract

Abstract

CHF experiments in confined spaces are performed for near-saturated demineralized water at atmospheric pressure with gap sizes of 3 mm,5 mm and 8 mm,and inclination angles of 0°,5°,10°,15°,20°,and 30°.Analysis of CHF data showes that CHF decreases as the inclination angle changes from 30° to full downward facing position（0°） and increases as the gap size varies from 3 mm to 8 mm.In the present study,certain transition angles are also identified for different gap sizes.For the gap sizes of 3 mm,5 mm and 8 mm,the transition angles are found to be 10°,15° and 20°,respectively.
