Experimental investigations has been done to find out the heat transfer characteristics and friction factor of water based Al2O3 nanofluids as a coolant in  brazed plate heat exchanger. Plate heat exchanger either use horizontally or vertically. The base plate of the plate heat exchanger was kept inclined at (0⁰, 30⁰ ,60⁰, 90⁰). The experimentation have been done on the two different concentrat...

In this paper, the heat transfer enhancement in a counter-flow double pipe exchanger with longitudinal rectangular fins on outer surface of inner tube was numerically investigated by ANSYS 20.R1 software using CFD package and finite volume method. Hot water flows at 60℃ while cold 25℃. The flow is laminar five mass rates from 0.012kg/s to 0.02kg/s) for hot side 0.01kg/s 0.03kg/s side. Two types...

In this paper, overall heat transfer coefficient and friction factor of water based γ-Al2O3 nanofluid in a double tube counter flow heat exchanger have been measured experimentally under turbulent flow condition. For better dispersion of γ-Al2O3 nanoparticles in distilled water, magnetic stirrer and ultrasonic vibrator (with a power of 240 kW and frequency of 35 kHz) were implemented. The stabi...

It is often difficult for chemical engineering students to obtain a clear understanding of the physical processes going on inside the complex industrial scale equipment they study in the laboratory. We are testing the hypothesis that computer simulations showing the solutions to the differential equations that govern the fluid flow, heat transfer, mass transfer, and chemical reactions within th...

Different techniques have been used to achieve a high heat transfer rate. Among them, one of the advanced is suspension nanoparticles in base fluids as water and coated with aluminum titanium. The present work has carried out on double pipe exchanger twisted tape insert twist ratio (y/w = 4 6) thickness (0.8mm) for investigation nanofluid counter flow arrangement under turbulent conditions. com...

Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...
