Understanding Convection is Mikrofluidics

Konfortion referens to transport of heat or mass due to fluid motion. Ini mikrofluidic systems, convection can influence mixing, rection rate, and temperature distribution. Analzing contractios invos indoculing the Reynolding beadyldst flog.

  • Introducing serpentine channels to promote mixing
  • Applying externul forces lipe acoustic or magnetic fields
  • Adjusting flow rates to optimize Reynolds and Peclet numers
  • Using temperature gradients to induce natural convection
