Performance of Fluids in a Silicon-based Continuous Inkjet Printhead Using Asymmetric Heating
  DOI :  10.2352/ISSN.2169-4451.2001.17.1.art00064_1  Published OnlineJanuary 2001

In this paper, we study the performance of a variety of fluids in a new continuous inkjet printhead that employs asymmetrical heating of a jet of fluid to cause it to deflect. The basic design and operation of the printhead is described in a companion paper in this same conference. We focus mainly on the performance of non-aqueous fluids, with some discussion of the performance of water mixed with common humectants.By examining the performance of a variety of fluids, we try to understand the mechanism causing the deflection. We compare our experimental results to the output of a Computational Fluid Dynamics (CFD) model of the device that is solved using finite difference Volume of Fluid (VOF) code. With our choice of fluids, we focus on the role played by the temperature dependence of the fluid viscosity on magnitude of the jet deflection.
