“…CFD mainly facilitates in prior evaluation of chemical processes via following five steps: (i) estimation of engineering design parameters, (ii) understanding the transport phenomena of chemical engineering processes under consideration, (iii) developing relationship between fluid mechanics and design objectives of system under consideration, (iv) design optimization and scale‐up of the system under consideration, and (v) safety assessment of postulated worst‐case scenario, which could be involved while the equipment is in operation. The inclusion of basic and advanced courses on CFD in the Chemical Engineering curriculum is thus felt to be of utmost importance in recent times as also reported by Adair et al An elaborated view of the use of various CFD models for understanding the dynamics of the flow structures and relating them with flow parameter optimization for design and scale‐up of multiphase reactors has been elaborated in Joshi et al and Mathpati et al…”

The largest network of fluid transportation in the world is through pipelines.During the transportation of fluids through pipes, several "fittings" are used in the piping system such as elbows, T-junctions, reducers, expanders, bends, couplings, valves, etc. The flow complexities in pipe fittings are accounted for the pressure drop in piping network design. The pressure drop is estimated using the loss coefficient or equivalent length method using standard charts. Computational fluid dynamics (CFD) is a reliable tool to estimate pressure drop and understand nonidealities in pipe fittings. The use of CFD in the advanced level course in transport phenomena/fluid flow for piping network design can help students to implement modern mathematical tools as well as evaluate standard protocols followed in the industries. In this article, an interactive teaching methodology has been implemented to investigate the hydrodynamics in various pipe fittings (elbow, bend, Tee, and reducer) by actually visualizing the flow. The three-dimensional flow visualization is used to demonstrate the nonidealities such as separation, swirling, dead zones, etc. The CFD simulations of pipe fittings provided a new learning experience to the students that would help them to predict the pressure drops in industrial piping network systems. The outcome from the students' survey showed that the proposed CFD methodology assisted them to gain a better understanding of conventional Chemical Engineering subjects of "Transport Phenomena" and "Fluid Dynamics" in an innovative way.

“…Also faculty do not get personally rewarded for innovative teaching at the same level as research (Felder, 1984) so providing little incentive other than personal satisfaction. While there are many innovative ideas and trends within today's teaching (Adair et al, 2014;Felder et al, 2000;Adair & Jaeger, 2013;Seymour, 2002), there is still the tendency to over-use the lecture-homework-quiz format. This is indeed an efficient method of delivering knowledge and skills, but it has never been shown to be effective at producing the critical, innovative thinking skills needed to solve difficult technological problems.…”

Critical thinking extends to all aspects of professional engineering, especially in technical development, and, since the introduction of the ABET 2000 criteria, there has been an increased emphasis in engineering education on the development of critical thinking skills. What is hoped for is that the students obtain critical thinking skills to complement their abundant logical thinking skills. Critical thinking is a developmental skill that cannot be taught simply by traditional methods, i.e., step-by-step instruction followed by repetitive skills, as used for logical thinking skills. The research and development reported here is concerned with outlining how students first can be alerted to what critical thinking is, and how critical thinking can be nurtured through practical experience with appropriate guidance and reinforcement. The module 'Introduction to Fluid Mechanics' has been selected to demonstrate how formal critical thinking components may be introduced with the development of principles of logic and an obligatory problem solving procedure. A method of assessment during various phases of critical thinking, i.e., initial design or set-up, testing of method or prototype, and evaluation of the results, of open-ended assignments in engineering for each year of the undergraduate course has been developed.

“…For example, in chemical engineering, it is not unusual for schools to offer elective courses in Computational Fluid Dynamics (CFD) and/or multiphysics modeling [5][6][7], but it would be quite unusual for these to be part of the core curriculum. To provide all students with some exposure to such software tools, it is therefore necessary to incorporate them directly into some common core courses.…”
