Turbulent contribution to heat loss in cavity receivers

Logie, William; Abbasi, Ehsan; Hughes, Graham; Pye, John


For the prediction of convective heat loss from solar concentrating receiver cavities a number of empirical correlations exist. Geometry and the inclination angle determine the degree to which natural convection can infiltrate the cavity and remove stably stratified hot air out through the aperture. This makes the task of defining characteristic lengths for such Nusselt correlations difficult, neither does their use offer insight as to how one might reduce heat loss through the use of baffles,...[Show more]
