Briefs about my research:
In this study the effects of corrugated absorber plate and using aerosol-carbon black nanofluid on heat transfer and turbulent flow in solar collectors with double application and air heating collectors, were numerically investigated. The two-dimensional continuity, momentum and energy equation were solved by finite volume and SIMPLE algorithm. In the present investigation all the simulations were done for two different angles of tilt of collector according to horizon, that these angles were the optimum ones for the period of six months setting. As a result the corrugated absorber plate was inspected in the case of triangle, rectangle and sinuous with the wave length of 1 mm and wave amplitude of 3 mm in turbulent flow regime and Reynolds number between 2500 to 4000. Choosing the proper geometry was carried out based on the best performance evaluation criteria (PEC), for collectors with dual usage and increasing the air temperature from collector inlet to outlet for air heating collector. The results revealed that using corrugated absorber plate has a considerable influence on flow field and heat transfer. For all times of the year the highest PEC was obtained for corrugated Sinusoidal model, however the highest temperature increase from inlet to outlet was obtained for rectangular corrugated model. Also it was understood that in the case of using air as a base fluid, whether for the case of temperature increment from inlet to outlet or the highest PEC, the optimum Reynolds is 2500. For each of the corrugated absorber plate with sinusoidal and rectangular models, the carbon black nanoparticles were added to air base fluid in volume fractions of 0.1% to1%. The results indicated that in sinusoidal model the nanoparticles volume fractions increase leads to heat performance coefficient increase and the best heat performance conditions were attained in volume fraction of 1% and Reynolds number of 4000 for both six months period. In rectangular corrugated model using nanofluid and Reynolds number increase do not worth and lead to outlet temperature decrease. Therefore for this model using air and Reynolds number of 2500 is recommended.

Who/What inspired me to research on this topic and over what time:
Our professor, Ghanbar Ali Sheikhzadeh, had a remarkable effect to inspire us for researching on this paper. On the other side, one way in order to reach the highest thermal performance in heat exchangers is to apply some changes in their geometry. Getting the heat exchanger jagged and grooved on the interior side is one of the methods for breaking the laminar sub layer and creating the local wall turbulence (due to repetitive flow separation and adhesion between successive grooves). This method decreases the thermal resistance and increases the heat transfer considerably. Stationary and rotational obstacles are good choices due to fulfill this demand.
