Keywords: tube inclination | heat supply and twist pitch

The present work deals with experimental studies on heat transfer and flow characteristic for buoyancy induced flow through inclined tubes inserted with twisted strips. The parameters varied during the experimetation are; tube inclination , heat supply and twist pitch. It was found that the percentage enhancement in heat transfer coefficient decreases with increase in pitch parameters and tube inclination.The flow rate decreases for lower values of pitch parameters and increase in the tube inclination.
