Investigation of thermal performance of an air-to-air thermosyphon heat exchanger using ε-NTU method
Investigation of thermal performance of an air-to-air thermosyphon heat exchanger using ε-NTU method...
Effect of nano particles on heat transfer in heat exchangers
concentric circular and sinusoidal double tube heat exchangers while hot pure water flows in the outer tube. The single-phase and two-phase models is used to simulate the nanofluid forced convection of 2% and 3% volume concentrations. The renormalization...
energy conservation by waste heat recovery in industry using thermosyphon heat exchangers
conservation of energy by waste heat recovery is important not only for cost reasons
Nanofluids effects on the evaporation rate in a solar still equipped with a heat exchanger
In this paper, the performance of a solar still equipped with a heat exchanger using nanofluids has been studied both experimentally and theoretically through three key parameters, i.e., freshwater yield, energy efficiency and exergy efficiency...
Heat transfer enhancement of pasteurization processes by using nanofluids.
Saving energy is a vital issue in industrial processes in these days. In order to produce the milk products, many exchangers and so much thermal energy are used in dairy industries. Plate heat exchangers play an important role in these industries...
Numerical Simulation of Fouling in Heat exchangers
Heat exchangers are an important part of industrial processes as they handle a major portion of total energy consumption. Fouling can have serious impact on the performance of heat exchangers and hence affect the economic performance of a process...
The effect of greenhouse vegetation coverage and area on the performance of an earth-to-air heatexchanger for heating and cooling modes
cooling and heating by using an earth-to-air heat exchanger (EAHE). This paper considers the effects of two parameters as independent variables including the area of greenhouse and the percentage of vegetation coverage inside the greenhouse...
Heat Transfer and Sensitivity Analysis in a Double Pipe Heat Exchanger Filled with Porous Medium
In this paper, 2-D numerical investigation and sensitivity analysis are performed on heat transfer rate and heat exchanger effectiveness of a double pipe heat exchanger filled with porous medium. The Darcy–Brinkman–Forchheimer model is applied...
Numerical Investigation of Heat Exchanger Effectiveness in a Double Pipe Heat Exchanger Filled With Nanofluid: A Sensitivity Analysis by Response Surface Methodology
In this paper, the Response Surface Methodology (RSM) and two phase mixture model are proposed to investigate the sensitivity analysis of heat transfer and heat exchanger effectiveness in a double pipe heat exchanger filled with Al2O3 nanofluid...
