In current study, the heat and mass transfer characteristics of a novel compact heat exchanger consisting of round bare tubes with diameter of 0.8 mm are studied under dehumidifying conditions.
One example is the front heat transfer system of road vehicles, where the air flow rate through the compact heat exchanger core is optimized for minimum vehicle drag using both wind tunnel tests and Computational Fluid Dynamics(CFD) simulations.
The numerical model for fluid flow and heat transfer the fin tube of compact heat exchanger was developed under the following assumptions:
Compact heat exchanger and cooling tower combination removes heat and stabilises temperatures in a variety of process industry applications.
The new compact heat exchanger unit ensures maximum efficiency of the heat transfer process which is achieved at the lowest energy cost.
CoolTube is an efficient compact heat exchanger. Following successful analysis by the computational fluid dynamics department at Huddersfield University in 2011, it is now growing in sales and is being bought by major brewers for pubs across the UK, Europe, South Africa and Australia.
Utilizing a compact heat exchanger (CHE) is one of the most important aspects in heat exchanger development over the years (Hesselgreaves 2001).
The system works by burning waste wood in the form of pellets in a combustor that generates hot air through a mile and a half of piping packed into a compact heat exchanger. The hot air powers a turbocharger, more usually found in Scania trucks.
Two general uses of this approach are flow through the fixed and rotating blades of a gas-turbine stage, and flow in the passages of a compact heat exchanger. In turbine and compressor bladings, general areas for design improvement are the shape of the profile (type, camber, and ideal flow angles) and its geometric parameters (blade-height-to-chord ratio and chord-to-length ratio); the constructive details of the leading and trailing edges (curvature around the stagnation point and trailing-edge thickness); the form, number, and location of the cooling holes; and the temperature and mass flow rate of the cooling fluid.
(2003) studied a compact heat exchanger with a three-pass configuration.
The new compact heat exchanger unit is reported to ensure maximum efficiency of the heat transfer process which is achieved at the lowest energy cost.
As part of the Kirklees Innovation Voucher scheme, Brewfitt Ltd approached Huddersfield University to undertake a study into thermo-fluid performance of the CoolTube, which was developed by Brewfitt in a bid to achieve a compact heat exchanger with a high effectiveness.
