Lian-Ping Wang, Southern University of Science and Technology in China has recently joined the Journal of Fluid Mechanics Editorial Board for JFM Rapids. To celebrate, Lian-Ping Wang participated in a Q&A with the Journal.
Journal of Fluid Mechanics: What originally drew you to, or excites you about fluid mechanics?
Lian-Ping Wang: I love mathematics and physics, and I often find physics and mathematics work together nicely in the study of fluid mechanics, plus now the use of computer science in fluid mechanics, making fluid mechanics really an interdisciplinary topic. The ever-increasing range of applications at all scales and in many fields also make fluid mechanics fascinating. Yes, I have met many interesting scholars through studying fluid mechanics problems.
JFM: Among current research, what papers do you most look forward to reading?
L-P.W: I love reading papers presenting new physical phenomena in fluid mechanics, derived from rigorous mathematical analysis or numerical simulations. I also like reading papers demonstrating exciting new applications of fluid mechanics, introducing clever analytical tools or designing a novel simulation method.
JFM: What are you currently working on that you’d like to tell us about?
L-P.W: My main interests are computational methods and turbulent multiphase flows. I was exposed to turbulent multiphase flows since I was an undergraduate student 40 plus years ago. Luckily, over this period of time, computational methods and the power of computers have both advanced so much that the complex problem of turbulent multiphase flows can now be approached much more rigorously than 40 years ago. Another interesting development during this period is the emergence and rapid advances of a new class of computational methods for solving complex flows, known as the mesoscopic methods based on solving a model Boltzmann equation, such as the lattice Boltzmann method. I am currently working on advancing mesoscopic methods to better solve turbulent multiphase flows, and to develop analytical models to treat rigorously the physics of turbulent multiphase flow such as turbulence modulation by solid particles and deformable droplets.
JFM: In which areas of Fluid Mechanics research do you expect to see growth in the next ten to twenty years?
L-P.W: From the fundamental viewpoint, I think fluid-mechanics problems involving multiple nonlinearities and multiple scales such as multiphase interfaces, thermal coupling, stratification, rotation, phase changes, will likely to be explored in the future due to their rich physical phenomena that are still poorly understood. On the other hand, fluid mechanics will find its way in addressing interdisciplinary application problems affecting our society such as renewable energy, biomedical, and space exploration.
JFM: What are some of the challenges facing the field today?
L-P.W: As more simulation and measurement tools become widely available, generating data for complex flow problems is easy. Understanding the physics of these flows and performing theoretical modelling are more challenging. It may also be challenging to attract young researchers and train them to master the research tools and at the same time perform impactful analytical work.
JFM: What drew you to moving to handling JFM Rapids, and how does your experience and expertise impact the journal?
L-P.W: I was invited by Dr. Caulfield to help handle JFM Rapids, with the anticipation that JFM Rapids may grow to disseminate the most cutting-edge impactful fluid-mechanics research. This is a good opportunity to be directly exposed to the best work in the field. I have had a long research career studying the fundamental issues in turbulent flow, multiphase flow, compressible flow and related analytical tools and computational methods, as well as their applications to engineering and environmental sciences. I have also been very lucky to meet many wonderful scholars in our fields. I hope to help maintain the great reputation of JFM while expand its readership.

In this blog for Data-Centric Engineering, Paul Clarke (Chief Technology Officer at Ocado) documents Ocado’s journey with building synthetic models of its business, its platforms and its underlying technologies, including the use of simulations, emulations, visualisations and digital twins. He explores the potential benefits of digital twins, including the opportunities for creating digital twins at […]
We invited Trautmann to tell us why he writes about Indian war elephants, and how. He touched on several topics in the process: the value of analytical accidents, the recovery of lost knowledge systems, and the power and pluralism of human logics.
