Research Projects

Electro-thermal analysis and design of microheaters and microsensors for precise control of heating profiles in drug delivery devices and test platform for advanced spray cooling technology. This research activity was performed in collaboration with Hewlett Packard Laboratories (Palo Alto, CA) and Hewlett Packard Technology Center (Aguadilla, PR).

Microheaters and Microsensors

Fundamental research on the bubble dynamics and heat transfer at the microscale in micron sized cavities. The thermal inkjet device (TIJ) was used as a test platform during this investigation. This project is a collaboration with Santa Clara University (Santa Clara, CA) and Hewlett Packard Laboratories (Palo Alto, CA).

Microbubbles and phase change

Fundamental studies of the conjugate heat transfer during droplet impact and liquid vaporization. Development of drop on demand spray cooling technology. This research activity is a long term collaboration with Santa Clara University (Santa Clara, CA) and Hewlett Packard Laboratories (Palo Alto, CA). Heat removal capabilities have been demonstrated in the order of 1kW/cm2.

Spray Cooling

1. Development of technology for wave energy conversion for power generation in the Caribbean.

2. Ocean Thermal Energy Conversion (OTEC): exploration into the feasibility of present technology to the production of energy using thermal gradients in the ocean.
