**Simulation of Leaky SAW Resonators on Lithium Tantalate Substrate Using COMSOL Multiphysics®

This talk deals with the design and simulation of leaky surface acoustic wave (LSAW) resonators on a 42° YX lithium tantalate (LT) substrate. LSAW resonators are the building blocks of resonator-type low-loss acoustic filters that are extensively used in today’s wireless communication systems. For the first time, the use of COMSOL Multiphysics® for the analysis of such LSAW structures is demonstrated. The one-port LSAW resonator is taken up as a test case and the effect of bulk wave modes, particularly the surface-skimming bulk wave, on resonator performance is simulated and discussed. Simulations are carried out for different thicknesses of aluminum thin film to find out the most suitable electrode height from a spurious-free passband performance as well as from a fabrication feasibility standpoint.

Modeling Lunar/Planetary Heat Flow — Opportunities and Challenges

Systematic measurements of heat loss from lunar/planetary interiors and their spatial variations are needed to estimate the net heat flow on the planetary body. This aspect in turn has several geophysical implications. Lunar surface and subsurface temperatures of moons are dictated by a complex interplay of a number of parameters. These surface and subsurface temperatures also manifest significant latitudinal, stratigraphic, and topographical variability. One way of understanding these aspects before any future in situ measurements are available is to conduct laboratory experiments on an analogous sample under a simulated lunar environment. However, laboratory experiments have certain limitations in terms of simulating parametric variation and long-term variability. At this point, the only way we can improve our current understanding of these aspects is through comprehensive numerical simulations. Keeping this in mind, a comprehensive three-dimensional finite element thermal model has been developed using the COMSOL Multiphysics® software to address some of these aspects. The model is designed to account for a complex geometry, different sizes, irregular meshing, and parametric-based variation in physics and boundary conditions. The model results have been validated through laboratory experiments. Some of the aspects and challenges in developing such a model for planetary surfaces will be discussed.

Heat Transfer Simulations Using COMSOL® for Industrial Challenges: IIT Gandhinagar Case Studies

This talk showcases some industry challenges that can be addressed through heat transfer analysis and the role of the COMSOL Multiphysics® software in those analyses at the Energy Systems Research Laboratory in IIT Gandhinagar. In order to understand the temperatures and thermal loads on an integrated detector Dewar cooling assembly of space-based optical spectrometers, we employed a combination of radiative heat transfer and ray tracing capabilities of COMSOL Multiphysics®. This model examines the temperature and heat flux on the spectrometer’s focal plane array in order to maintain its low temperature (~ 90 K) for maintaining image resolution. In the second application, a catalytic heat exchanger is modeled by coupling heat transfer and endothermic chemistry for methanol steam-reforming applications. Within the heat exchanger (reactor), methanol is converted to hydrogen through steam reforming; the thermal requirements for this endothermic chemistry are provided by heat transfer from hot combustion gases on adjacent layers. Fluid flow, heat transfer, and complex elementary surface chemistry are all simulated using COMSOL Multiphysics® modules. In the third application, a vanadium redox flow battery (VRFB) for electronics cooling applications and power delivery is studied using COMSOL Multiphysics®. In this model, heat transfer, fluid dynamics, and electrochemistry are coupled and this helps in investigating the influence of flow field geometry, flow rate, and porous electrode properties on the performance of a miniaturized VRFB.
