COMSOL Expert Needed for Coupled Ultrasonics, Acoustic Streaming, Fluid Flow and Heat Transfer

I am looking for an experienced COMSOL Multiphysics specialist to support the development of a coupled numerical model involving ultrasonic excitation, structural vibration, acoustic streaming, viscous fluid flow, and heat transfer. The application involves a shell-and-tube heat exchanger operating with a high-viscosity fluid under low-flow conditions. The objective is to investigate whether externally applied ultrasonic excitation can enhance convective heat transfer through acoustic streaming, secondary flow generation, and thermal boundary-layer disruption. The ideal candidate should have demonstrated hands-on experience in some or all of the following areas: * COMSOL Acoustics Module * Acoustic streaming * Pressure Acoustics and/or Thermoviscous Acoustics * Acoustic–structure interaction * Solid Mechanics and structural vibration * Laminar or low-Reynolds-number viscous fluid flow * Heat Transfer in Fluids and Solids * Multiphysics coupling between acoustics, fluid flow, and heat transfer The work may initially focus on a reduced representative geometry to evaluate the physical feasibility and computational requirements before considering a larger-scale model. Applicants should briefly describe: 1. Their previous experience with acoustic-streaming simulations in COMSOL. 2. Any previous work involving ultrasound, acoustofluidics, vibration, heat transfer, or viscous fluid flow. 3. The COMSOL physics interfaces and modelling approach they would recommend for this type of problem. 4. Examples of relevant previous simulation work, publications, screenshots, or technical reports, where available. Please note: General CFD or general COMSOL experience alone is not sufficient. Specific experience in acoustics, ultrasound, or acoustic streaming is strongly preferred.
