Johan Sundin

Johan Sundin is a researcher at KTH Royal Institute of Technology's School of Engineering Sciences, Department of Engineering Mechanics. His work focuses on fluid mechanics with particular expertise in liquid-infused surfaces, turbulent flows, and flow-structure interactions. Previously affiliated with the Linné Flow Center (FLOW) and Mechanics, Stability, Transition and Control research group, he continues to contribute significantly to the field of fluid dynamics.

Dr. Sundin completed his doctoral dissertation titled 'Interaction of flows with slender structures and liquid-infused surfaces' in 2022 under the supervision of Professor Shervin Bagheri. His educational background demonstrates strong foundational knowledge in engineering mechanics with specialized training in computational fluid dynamics and experimental techniques.

His research interests span multiple interconnected areas including liquid-infused surfaces for drag reduction, heat transfer enhancement mechanisms, capillary wave phenomena, and soft material flow sensors. Sundin's work uniquely bridges fundamental fluid dynamics with practical engineering applications, particularly in micro air vehicle technology and surface engineering. His research demonstrates how surface textures and liquid-infused configurations can manipulate flow properties for improved performance.

Analysis of Sundin's publication record reveals a consistent focus on liquid-infused surfaces (LIS) and their applications. His work explores both fundamental mechanisms (capillary waves, surfactant effects, contact line dynamics) and practical implementations (flow sensors, drag reduction systems). A notable trend is his investigation of LIS performance under turbulent conditions, addressing critical challenges like drainage resistance and heat transfer enhancement. His research has evolved from basic flow-structure interactions to increasingly sophisticated multi-phase flow systems with practical engineering implications.

Sundin has received research funding from prestigious sources including the Knut and Alice Wallenberg Foundation (KAW 2016.0255) and the Swedish Foundation for Strategic Research (FFL15:0001). His collaborative work spans multiple institutions, with frequent co-authorship with researchers from KTH's Engineering Mechanics department and international partners.

His research is conducted within KTH's advanced fluid mechanics facilities, particularly those associated with the Linné Flow Center. Sundin utilizes both computational approaches (volume-of-fluid methods, molecular dynamics simulations) and experimental techniques to investigate complex fluid phenomena. His work on soft material flow sensors demonstrates practical applications of fundamental research, creating durable, lightweight sensing solutions for micro air vehicles.
