Rajesh Bhaskaran’s work seeks to promote the “democratization of simulation” through effective integration of simulation tools into engineering education. He directs the Swanson Lab and has helped introduce industry-standard simulation tools into Cornell courses covering fluid mechanics, heat transfer, solid mechanics, and numerical analysis. Dr. Bhaskaran has led the development of SimCafe.org as an online portal for learning and teaching finite-element and CFD simulations. SimCafe is used worldwide in courses as well as for self-paced learning by students and industry professionals. He has developed a unified methodology for using simulation in disparate lecture-based and lab courses. This methodology teaches students to approach simulations like an expert rather than just pushing buttons and accepting results at face value. Dr. Bhaskaran’s professional interests include engineering applications of simulation technology, reliable deployment of advanced simulation by generalist engineers, and conceptual change in learners using simulations. He has organized two international workshops on simulation in engineering curricula.
Computational fluid dynamics (CFD) aims to analyze and solve fluid mechanics problems within a variety of practical contexts. In particular, CFD approximately solves the mathematical models in fluid mechanics using numerical solution strategies with computer modeling software. Through the use of modeling software, you will leverage the computational power of the computer to complete calculations that would otherwise be impossible to do by hand. You will also generate clear visual representations of your solution that make interpretation by humans much easier and enable us to develop physical intuition. To ensure that your solutions accurately represent reality, however, you need to first understand how the "black box" of your modeling software functions and have methods to verify and validate your results.
The framework used in this course for solving fluid dynamics problems can be applied to a wide array of situations and contexts. You will work on a 2D incompressible laminar flow problem in Ansys. Working with 2D flow simulations will help prepare you to create reliable fluid flow simulations for more complex 3D applications such as a car body, fan, and airplane.
While 2D simulations are a good place to begin, many of the real-world applications of simulation require simulating 3D conditions. In this course, you will work on a 3D turbulent flow problem in Ansys. You will apply the ideas covered in the previous course on 2D laminar flow, now extending to 3D turbulent flow, which is relevant for many industrial applications of simulation.
Rotating machinery is very important to consider in practice because it exists all around us in many forms, such as wind turbines, compressors, and fans. In this course, you will work on rotating machinery flow problems. This problem extends the same underlying physics and governing equations applied to 3D flows, with the added complexity of a moving physical body.
In high-speed flow, density changes are important to account for in order to accurately simulate the flow. In this course, you will work on compressible flow problems in Ansys. A classic example of such a flow problem is airflow over an airplane body. You will solve the governing equations for this type of problem and simulate the high-speed flow over an airplane body.
