Introduction The dynamics of non-Newtonian fluids has been a widespread area of research because of its ever-increasing applications in chemical and process engineering.
In recent years nanofluid have impress the attention of science and engineering fields because of its innumerable industrial and nano-technological applications.
The thermal radiation effects on different fluid flows have many industrial and engineering applications, such as space technology, nuclear power plants, in aircraft and also in gas turbines, engineering processes operating at high temperatures and thermal radiation is also useful in controlling heat transfer.
· The nanoparticles are used to control the heat transfer rate in many industrial and engineering applications.

Introduction General tendencies in creating designs of advanced engineering structures of different functional area in many industries (chemical and food, power engineering and shipbuilding, aerospace manufacturing, etc.) are associated with a reduction in mass of products [1-5], with the use of materials having improved mechanical [6-9] and operational characteristics [9-13], and also with the introduction of modern treatment technologies [14-18].

Introduction Ceramic composites such as silicon carbide reinforced silicon carbide composites (SiC/SiC composites) are candidate materials for high heat flux components because of their high-temperature properties [1].
Because of the brittleness of the ceramic materials, FEM calculations were conducted assuming linear elastic behavior in two-dimensional plane strain.

Thirdly, Sr or Ca doped-LaMnO3 is a candidate cathode material of solid fuel cell [6].
Methods The crystal structure of a material at a given temperature and pressure can be predicted by minimizing its free energy with periodic boundary condition.
Thus for a cubic material:
This technique has been used for simulation of many kinds of materials [19-24].

Though there have already appeared a few blast furnace expert systems of close loop [5], but for the furnace fed with poorer raw materials, the close-loop expert system did not succeed as expected [9].
In consideration of its own raw materials condition and real demands of BF no.8, the goal of the expert system development was positioned as an open-loop control system focused on furnace heat, gas distribution and abnormal furnace conditions.
To adapt to the variation of operational targets, raw materials conditions, furnace working profile and so on, the operators have to take a different strategy in the furnace control.

Wettability alteration is one of the mechanisms of (EOR) by alkaline flooding and so wettability plays a key role in determining fluid distributions and consequently the multiphase flow and transport in petroleum reservoirs.
In fact, nanoparticles [29-31] are very active and energetic materials with a high tendency to form nanotextured surfaces in combination with surfactants, resulting in a significant change in the interfacial properties of the system.
Experimental Details Materials and Methods 1- Synthesis of SiO2 nanoparticles The synthesis of spherical fine SiO2 nanoparticles was prepared from Si (OC2H5)4 (TEOS) by sol gel and partially acidic hydrolysis method. 5 ml acac (acetyl acetone) surfactant in 2 gr. citric acid solution added during 0.5h with stirring at 40-50° C.
In addition, SiO2 (1) 3% (54.51 altered to 46.83) and for concentration of 8% (50.80 changed to 47.42) could indicate important reduction in S.T after the annealing process and surface engineering of nanoparticles in based distilled water (S.T for H2O= 72.566 mNm-1).

This is may be due to the impact of harsh atmosphere on the efficiency of the PV modules, mainly soiling and materials degradation [10-12].
As results, Greenius give the energy outputs for the simulated system in different times steps: hourly, daily, weekly, monthly and annual as well as some key results such as the performance ratio and yield field in the case of PV systems.

Decreasing the combustor temperature will also impact on the need for costly combustor materials and thermal barrier coatings on the combustor liner, enabling a more resource efficient manufacturing.
Decreasing the temperature leads to significant benefit in terms of diminished NOx production, reducing the environmental impact of European air transportation, as well as a need for less temperature resisting materials for the combustor, contributing to a more resource efficient engine.
However, high temperature regions on the walls near the turbine combustion regions may occur, which raises the issue of high temperature resistant materials required for these regions, and / or of developing light and efficient cooling systems able to maintain the wall temperature below the material resistance limits throughout the turbine.
The key finding of these studies is that fully developed turbulence cannot be assumed in the turbine channels, so RANS numerical simulations are not suited for the problem, requiring more advanced LES numerical simulations.
