Therefore, thermal control has a crucial factor in the design of electronic equipments due to undesirable increased thermal stresses and mechanical faults in the system. In this work, flow and heat transfer from semi spheres by placing at different angles of 40o, 60o, 90o and without angle in channels were numerically examined. The boundary conditions were indicated as three dimensional, incompressible, fully developed and laminar flow for converging-diverging channels having eight semi-spheres with different angles. The continuity, Navier-Stokes and energy equations were solved numerically by using Ansys-Fluent Air was taken as working fluid. Inlet temperature of the air to the channel and surface temperatures of the spheres are K and K, respectively. The effects of different locations of semispheres with as angle on the heat transfer and pressure loss coefficient increment and flow structure in the case of different Re numbers of, and were investigated. The results were presented as variations of average Nusselt number, outlet temperature and heat flux and also pressure loss coefficient of the fluid according to different Re numbers. Besides, temperature and velocity contours and also velocity vectors among the spheres and along the channel were analyzed. In addition to these, mean Nusselt numbers and heat fluxes for each of eight semi spheres were researched at different Re numbers. The obtained results show that the location angles of the semi spheres in the converging-diverging channel have a great importance on account of flux and mixing of the fluid among the spheres in order to make cooling effective. The highest heat transfer was also attained for 40o angle comparing with without angle. Keywords: Converging-diverging channel, Placement angle, Semi sphere, Heat transfer. Especially, cooling process of the electronic equipments looks like the flow in converging-diverging channels and the cooling can be enhanced with use of they. However, heat transfer has a great important role in the design of various heat exchangers, nuclear reactors, solar collectors, heaters, coolers, internal-combustion engines, combustion chambers, electric machines etc. Coordinat Bornova Da Seks is required that the heat transfer is taken the highest values in order to design of compact devices. Nowadays, various type heat exchanger designs have been improved. Heat transfer coefficient belonging to surface geometry of these heat exchangers and flow properties with pressure loss coefficient should be determined. One of the heat transfer increment methods is continuous renewed of boundary layer. For this aim, shifted plate serials have been investigated in literature and it has been shown that the heat transfer coefficients can be increased. One of the developed methods for enhancement of heat transfer surface area and the most important for improving of heat transfer coefficient by forming flow mixture section is communicating converging diverging channels. By means of these channels, enhancement in heat transfer can be carried out by increasing surface area in unit volume and especially by composing mixture section. Pressure drop also increases with increasing heat transfer at flow on Coordinat Bornova Da Seks surfaces. Therefore, main goal for using of these surfaces is that when it is provided maximum enhancement in heat transfer, increment in pressure drop is obtained by minimizing of flow rate. The main purpose should be become to determine optimum values which increase the system performance. Converging-diverging channels as periodic has become subject of interest for many researchers. Sparrow and Prata [1] investigated flow and heat transfer with Reynolds number between and at converging-diverging conic channels with unconnected as periodic both experimental and numerical. It was shown in study that pressure loss was little more according to flat tube and Nusselt number as depending on Prandtl number. Patankar [2] studied flow and heat transfer under fully developed flow conditions in rectangular cross-section channels that were periodically variable cross section in flow direction. It was found that the uniform wall temperature was similar due to the fact that the velocity and temperature profiles changed periodically in the modules. It was determined that the temperature area in a given wall heat flux periodically repeated itself. With the concept of periodically fully developed flow and solution method, Patankar developed the first theorem of such heat transfer mechanisms. Here, he determined that the Nusselt number in the periodically fully developed flow was very high relative to Coordinat Bornova Da Seks smooth channel flow and was a function of the Reynolds number. Kelkar and Patankar [3] investigated flow and heat transfer in channels with fins by studying constant fluid properties and considering flow as two-dimensional. In this study, two parallel plates were used and the flow was simulated by placing fins on the surfaces of the parallel plates. The calculations were examined by changing the variables such as Reynolds number, Prandtl number and fin conductivity in different geometric parameters. Also, it indicated that the increase in pressure drop helped to increase the heat transfer. Wang and Vanka [4] numerically examined flow and heat transfer in periodic sinusoidal channels. Their studies showed that heat transfer was increased in such channels but the increase in pressure loss was less than the increase in Nusselt number.
