What next after BTech?

Sandeep June 17, 2021

BTech, BE, or Bachelors in Engineering is one of the best and popular professional courses you could do after your school education. At that time the confusion was all about which college/university and which branch to choose? But now, towards the end of your four years of a beautiful journey called the Bachelor’s in Engineering, you must be worried about what should be the next step. It must be challenging, especially if you are not able to find a job through campus placements. The current situation is even challenging due to the pandemic (Covid-19) all around.

This world is full of opportunities; you need to utilize this time to upgrade your skills and education. Remember the quote by Benjamin Franklin, ” An investment in knowledge pays the best interest”. No pandemic or recession can take away your knowledge, but you can use it at the right time, so be fully prepared when the opportunities knock at your doors.

Understanding the CFL Number: Physical significance and Best Practices

Convergence in CFD refers to the process where the solution of the simulation steadily approaches a consistent value as the number of iterations increases. A converged solution indicates that the simulation has stabilized and is no longer changing significantly with further iterations, signalling that the results are reliable. Achieving convergence is often linked to factors like mesh quality, boundary conditions, time step size, and numerical methods.

One of the key factors contributing to the stability of CFD simulations is the Courant-Friedrichs-Lewy (CFL condition), a crucial condition that governs the simulation. The CFL condition ensures that the solution updates are synchronized with the physical constraints of the flow, which is critical for maintaining stability and accuracy in the simulation. By adhering to the CFL condition, CFD experts can produce reliable results for a variety of engineering applications. In this discussion, we will explore the importance of the CFL condition and its role in CFD simulations.

Understanding the Pillars of Numerical Schemes: Consistency, Stability, and Convergence

In the realm of numerical methods, solving Partial Differential Equations (PDEs) plays a fundamental role in various scientific and engineering applications. However, directly solving PDEs analytically can be a daunting task for many complex problems. Hence, numerical schemes come to the rescue, offering a way to approximate solutions to these intricate equations. But how do we ensure that these numerical approximations are reliable and accurate? This blog delves into three essential concepts – Consistency, Stability, and convergence, which form the foundation for validating numerical schemes. The concepts will be explained in the context of 1-dimensional diffusion equation for simplicity.

The Y Plus Concept: Key to Boundary Layer Analysis

When we think about the sleek design of modern aircraft, our focus often turns to their impressive speed, fuel efficiency, and advanced technology. Yet, there exists an unseen force that significantly influences these attributes: the boundary layer, a thin region in which viscous forces are significant and within which the flow is rotational. This thin layer of air adhering to the aircraft’s surface plays a pivotal role in key aerodynamic factors such as drag, lift, and heat transfer.
