First we need to understand what the differences are between counter flow and parallel flow. As a brief description; the term refers to the relationship between the flow directions of the hot and cold fluids. With parallel flow the fluids are travelling through the heat exchanger in the same direction where as a counter flow installation will have the fluids flowing against each other in opposite directions.
The amount of efficiency gained by using a counter flow system depends on several factors including the flow rates and temperatures (these affect the efficiency on their own) but it will be most noticeable in a larger cooler.
In this tutorial you will learn to simulate Heat Trasnfer in counter flow using Ansys Fluent. In this tutorial we will use DesignModeler and Ansys Meshing too.
Ansys Fluent – Elbow 2D (Steady & Transient Simulation)
Pipe Fittings are Piping component that helps in Changes the direction of the flow such as elbows, tees. Changes the size of the pipe such as reducers, reducing tees.
Ansys Fluent – Fluidized Bed
A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.

The NACA four-digit wing sections define the profile by:
First digit describing maximum camber as percentage of the chord.
Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.
OpenFOAM vs ANSYS CFX
OpenFOAM is the free, open source CFD software developed primarily by OpenCFD Ltd since 2004. It has a large user base across most areas of engineering and science, from both commercial and academic organisations.
OpenFOAM – Units
In continuum mechanics, properties are represented in some chosen units, e.g. mass in kilograms (kg \relax \special {t4ht=), volume in cubic metres ( 3 m \relax \special {t4ht=), pressure in Pascals ( −1 −2 kgm s \relax \special {t4ht=).
