Critical Heat Flux (CHF) in a non-uniformly heated tube is very important factor in designing boiling two phase flow system. Although many investigations of CHF have been conducted under uniform heat flux and vertical upward flow condition, water tubes are affected by non-uniform heat flux distribution under inclined orientation in actual boiling system. In this series of studies, the non-uniform heat flux distribution has been realized by using the Joule heating and CHF was measured under several inclination angles, i.e. 15, 30, 45 and 90 degree. The CHF characteristic was depended on a combination of the tube orientation and the location of the maximum heat flux along the circumferential direction.
