چکیده
|
The inclusion of complex obstacles within solar channels is the aim of this article. two obstacles of the form ꞌ+ꞌ interlaced within a two-dimensional and rectangular channel are the subject of our study. the fluid is newtonian, turbulent, incompressible and has constant properties. the reynolds number varies from 12,000 to 32,000 with a constant temperature along the upper surface of the channel. the thermal and dynamic analysis of the channel’s internal structure has been carefully processed. different fields of speed and heat, with various profiles of frictions and heat exchange coefficients, have been included in this research. future work will involve more complex geometries and using nanofluids to assess the optimum conditions for heat transfer enhancements.
