(Approximate reading time: 5mins) Imagine we would like to simulate the flow of air around the wing of an airplane in order to calculate forces such as drag and lift, which are necessary for design purposes. Typically, we would use CFD (computational fluid dynamics) which uses an imported mesh, along with other inputs such as freestream velocity and angle of attack to simulate the flow around the wing. Then, the results are postprocessed to calculate the forces of interest. This...

(Approximate reading time: 5mins) In the recent release-22.3.3.0 of Flow360 a new point monitoring feature has been added to help users track time history of flow variables like velocity and pressure. This is a useful feature for acquiring physical quantities of interest in unsteady simulations as well as diagnosing solver divergence without dumping volumetric solution files frequently. Some applications of the feature include probing pressure on the wing surface to compare against pressure tap measurements and probing flow velocities at...

In this third and final installment, we present the results obtained from our extensive parameter study of an eSTOL aircraft using computational fluid dynamics. As we have mentioned in the previous articles, it is useful to study the individual components of an eSTOL aircraft to get a better understanding of the fluid dynamics involved. Be sure to check out PART I of the series to get a better understanding of why such a study is important and PART II to...

In PART I of this series, we presented why an eSTOL aircraft is important for future urban transportation and laid the foundation for carrying out a systematic study of its fluid dynamics. Here, we will discuss several propulsion approximations which are used in this context and how we can use the Finite Volume technique to model the associated Navier-Stokes equations. Part III will showcase the results from this study and how they helped us to better understand the fluid dynamics...

In this article we describe our efforts in collaboration with Electra (https://www.electra.aero/) to model an eSTOL aircraft using computational fluid dynamics. The full article consists of three parts: Part I provides essential background motivation for carrying out this study and how we section the full problem into smaller pieces. Part II will detail the modeling strategy and discuss the computational fluid dynamics approach. Part III will showcase the results from this study and how they helped us to better understand...
