Örnek Metin	The objective of this thesis was to understand ow phenomena inside chevron type plate heat exchangers. To reach this goal, several visualization experiments designed and conducted. Also Large eddy ow simulations were made. This simulations validated with visualization experiments and pressure drop experiments. The ow visualization results showed that rather than helical or cross ow structure, a combination of two structures exists inside the CPHE channel geometry. Visualization and pressure drop experiments validated the LES results. LES estimated the friction factor with maximum 5 percent error. Mixing study proved there is asymmetric mixing through the channel. To understand transition inside the channel a power spectrum of velocity magnitude of speci ed points was reported and results showed that between Re = 265 and Re = 275 there is a signi cant raise at turbulent intensity where seems the transition takes place.
