The purpose of this paper is to formulate the heat transfer needed to generate continuously the steam from the “Linear Fresnel concentrator Steam Generator” according to its dimensions. For more detail information refer to the article "Desalination of seawater by successive heating of thin layers of water using solar radiations from a Fresnel concentrator"[1], the preprint "Detail Design - Linear Fresnel concentrator Steam Generator"[2] and the preprint Steam Flow formulation of the Linear Fresnel concentrator Steam Generator[3]. The heat transfer flow assessment depending of many dimensions is the key point out put of this paper. At the glance, these dimensions are the geometry of the Linear Fresnel Concentrator, the tilt to the sun's rays, the length , the radius of the tangled cylinders, the thickness of the annulus spaces and the cavity between the composed device absorber and mirror. The device absorber is composed of the tangled cylinders and the steam collector. Note that the known LFR applications for both industrial and power sectors requires medium temperatures ranging from 100°C to 250°C. The flat plate solar collectors are suitable for low temperature applications maximum up to 80°C and parabolic concentrators are suitable for high temperatures applications above 300°C. Hence, the present work will focus on LFR with parabolic concentrator because sea water desalination requires reaching the boiling point under pressure near atmospheric pressure which is 100 °C. Furthermore, the diameter of absorber device for parabolic concentrator may vary from 5 in to 10 in which is much greater than tubes dimensions for trapezoidal cavity. Then, this dimension fact allows efficient flow water circulation and meaningful steam flow generation.[1] touzani, s. (2019, March 28).
