Issue Date: | Nov-1988 | Citation: | Chew, T.C.,Wijeysundera, N.E.,Tay, A.O. (1988-11). Experimental study of free convection in compound parabolic concentrator (CPC) cavities. Journal of Solar Energy Engineering, Transactions of the ASME 110 (4) : 293-298. ScholarBank@NUS Repository. | Abstract: | An experimental study of the free convection heat transfer between the cylindrical absorber and the flat top of a compound parabolic concentrator (CPC) is described. Results are obtained for a range of absorber temperatures and four CPC cavity heights. For similar conditions of operating temperature, the heat transfer from a cylinder in free air is about 30 to 50 percent higher than in a CPC cavity. Two correlations for Nusselt and Grashof numbers have been obtained using the equivalent length and the cavity height as the characteristic length of the system. | Source Title: | Journal of Solar Energy Engineering, Transactions of the ASME | URI: | http://scholarbank.nus.edu.sg/handle/10635/58267 | ISSN: | 01996231 |
