A multi-scale conjugate heat transfer modelling approach for corrugated heat exchangers

Experimental Heat Transfer Studies of Water in Corrugated Plate Heat Exchangers: Effect of Corrugation Angle

In the present investigations heat transfer studies are made in three different types of corrugated plate heat exchangers having a length of 30 cm and width of 10 cm. The corrugated channel has a spacing of 5 mm. Three different corrugation angles are used in this study which are 30 0 , 40 0 and 50 0 . Water is taken as test fluid as well as the heating medium. The wall temperatures are measure...

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer

The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...

Application of ZnO/TiO2 Nanocomposite for the Improvement of Heat Transfer Coefficient in Tube Heat Exchangers

The potential of nanofluids for the improvement of heat transfer coefficient in various heat exchangeequipment has been considered and studied as a major application during recent decades. In this research,heat transfer coefficient of ZnO, TiO2 and ZnO/TiO2 nanofluids in a shell and tube heat exchanger has beenstudied experimentally. ZnO nanoparticle was synthesized through pre...

Heat Transfer to Separation Flow in Heat Exchangers

Heat Transfer Modeling of the Ground Heat Exchangers for the Ground-Coupled Heat Pump Systems

Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space air conditioning in buildings due to their reduced energy and maintenance costs. The efficiency of GCHP systems is inherently higher than that of the traditional options because it utilizes the ground which maintains a relatively stable temperature all the year round as a heat source/sink. Compared with tr...
