| Abstract | ||||
| Forced convection heat transfer experiments were provided to study the effects of tripping wire rings on the average heat transfer from a cross circular cylinder. The experimental data have been obtained When the test tube is covered by a number of tripping wire rings as well as the results obtained when the test tube is bare. The number of the tripping wire rings ranges between 0 and 53. The results have been presented in terms of Nusselt number and Reynolds number as well as the pitch to-diameter ratio of the tripping wire rings. Wind tunnel experiments extended over the range of the frec stream Reynolds numbers from 7.19x103 to 5.97x104. The pitch-to-diameter ratio varies between 0.172 and 1.131. The experiments are carried out for a constant rate of heat flux. The values of the average Nusselt number are fitted in a correlation. The correlation indicates that the Nusselt number is a significant function of Reynolds number and pitch to-diameter ratio. The augmentation of heat transfer varies from 13% to 62% as the pitch to diameter ratio varies from 1.131 to 0.172. | ||||
