Convective heat transfer occurs when there is an energy exchange between a flowing fluid and a solid body. This energy exchange or heat transfer occurs at the surface of the solid which is in contact with the fluid and is primarily governed by the temperature difference between the solid and fluid. The term “forced convection” is used when the motion of the fluid is driven by external means, such as a pump or a suction device. When the fluid moves because of buoyancy, the convective phenomenon is typically referred to as “natural convection”; examples include hot air balloons, blood circulation, etc. In most industrial applications, forced convection is used for effective and efficient heat transfer in applications like steam turbines, heat exchangers, etc. When the forced fluid flow is turbulent, it increases the mixing rates and eventually leads to an increased heat transfer compared to a laminar fluid flow. These heat transfer rates can be calculated with the help of engineering simulations. In this course, we consider a turbulent flow through a pipe with a heated section at the middle of the pipe.

This SimCafe course was developed by Dr. Rajesh Bhaskaran, Swanson Director of Engineering Simulation at Cornell University, and Yong Sheng Khoo in partnership with Ansys. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. In this course, we will learn to model the turbulent forced convective heat transfer through a pipe by following the end-to-end workflow in Ansys Workbench.

In a flow network, the flowing fluid encounters devices and attachments such as valves and bends. In addition to this, the fluids also may experience sudden expansions or contractions during the flow. Due to these inevitable pipe fittings and designs, the fluid experiences a loss of energy. In many industries, such as power generation, these losses compound and could become significant. In this Sim Cafe course, we consider steady laminar flow through a pipe with sudden expansion to understand the energy loss due to the expansion using Ansys Workbench.

A jet, which is a type of free shear flow, is exhaust from a confined source such as a nozzle into the quiescent surrounding. From an engineering standpoint, the jet centerline velocity, spreading rate, and penetration length are the parameters of interest. Based on the flow properties, jet flows can be laminar or turbulent. In this SimCafe course, we will learn to set up the models in Ansys Fluent and compare the laminar and turbulent jet flow results. We will also discuss the importance of the k-epsilon turbulence model in this course.

The Mach number, which is the characteristic non-dimensional number often used to describe the velocity of the object with respect to the speed of sound. At these speeds, shock waves, which are sharp spatial discontinuities in the flow properties such as density, velocity, and pressure, are created. Due to sudden changes in flow properties such as pressure, it becomes important to study the effect of a shock wave on the moving object for structural integrity and stability. In this SimCafe course, we will learn how to model a supersonic flow over a wedge using Ansys Workbench.
