Experimental Study of the Heat Transfer Enhancement in Concentric Tubes With Spherical and Pyramidal Protrusions
In the current research project, the thermal performance of a series of newly designed mixers has been investigated. Each mixer has two concentric cylinders comprising two annular slot flow channels around a solid cylindrical rod at the center. In each mixer, the first cylinder around the central solid rod has either spherical or pyramidal protrusions throughout the outer surface. It has been o...
متن کاملCompact Heat Exchangers for Microturbines
With distributed power generation market, the most economical solution today is to generate power through small gas turbine systems, arbitrarily categorized as microturbines (5 – 200 kW) and miniturbines (200 – 500 kW). The thermal efficiency of such microturbines is about 20% or less if no recuperator is used in the system. Using a recuperator (regenerator can also be considered but has a numb...
متن کاملFluid 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) ...
متن کاملDevelopment of C - SiC ceramic compact plate heat exchangers for high temperature heat transfer applications
This paper investigates the use of polymer and liquid silicon infiltrated carbon/siliconcarbide composite (C-SiC) materials for the development of inexpensive compact heat exchangers, as part of efforts for thermochemical hydrogen production. These heat exchangers will be capable of operating in the temperature range of 500 to 1400°C with highpressure helium, liquid fluoride salts (a potential ...
متن کاملModel Based Control of Compact Heat Exchangers Independent of the Heat Transfer Behavior
Compact heat exchangers have a wide range of applications where standard control strategies typically rely on the knowledge of the heat transfer model and thus on the overall heat transfer coefficient. In particular for compact plate heat exchangers, the overall heat transfer coefficient strongly varies with the manufacturer’s plate design and has to be identified by means of extensive measurem...
