Adding epoxy divisions and therefore reducing the area available for heat transfer by ~18%, results in up to a 5x increase in heat transfer rate at a given superheat. This result is explained by examining the nature of the bubble nucleation, growth, and departure process. The addition of non-conductive epoxy imparts order to the resulting vapor and liquid flows, which helps draw cool liquid to the surface and promotes departure of nucleating bubbles. While less of the surface area is available to transfer heat, this spatial order enhances the ebullition cycle and also delays dry-out. Figure 5 shows with the addition of two and four epoxy divisions per centimeter (N = 2 cm−1 and N = 4 cm−1 designs), the heat transfer rates steadily increase as compared to the bare surface. The performance enhancement reaches a maximum at a Bond number of unity,  = 1, and then decreases for smaller Bond numbers (N ≥ 6 cm−1). As the Bond number decreases, two factors affecting performance arise. First, the pitch between the epoxy divisions becomes smaller than the nominal bubble departure diameter, and secondly, the effect of surface tension becomes more pronounced. For N ≥ 6 cm−1 bubbles grow to diameters wider than the pitch between epoxy divisions before they can depart. This impedes the counter flow of cooler liquid returning to the surface and disrupts the desired spatial ordering of flow fields. Additionally, for BoP < 1 the effects of surface tension on the bubble departure process is evident, where the non-wetted base area beneath a bubble can grow to the entire width of the copper section (see supplementary movies). This is particularly evident for the N = 12 cm−1 design, which has a Bond number of BoP = 0.13, and shows performance worse than bare copper. In this case, the reduction of area available to conduct heat and the adverse effects of surface tension have outweighed any potential improvements associated with ordered flows. A decrease in HTC and CHF of approximately 25% as compared to a bare copper surface is seen.

Land Rover Chief Design Officer, Gerry McGovern, said: “We call the Velar the avant-garde Range Rover. It brings a new dimension of glamour, modernity and elegance to the brand. The Range Rover Velar changes everything.”

The Land Rover Route Planner app enables you to program a route in advance on a smartphone, which will then automatically be uploaded to the system once you’re in the vehicle. And because Touch Pro Duo provides true door-to-door routing, it can help you complete the final stage of your journey on foot or using public transport by seamlessly transferring guidance back to your phone once you park the vehicle.

"As I have said before, I am very proud of the bipartisan work we have done to assemble this package of reforms to the budget and appropriations process. However, as I have raised for weeks, the lack of an agreement between Senate leadership on a fair and bipartisan process for floor consideration opens up our final product to partisan mischief that frankly could undo our work and worse, actually make the budget process even more difficult."

Having a 4,000mAh battery, Honor 8C is targeted at users who don’t really like to hook up their smartphones to chargers every night. I used this smartphone with that expectation in mind, and I’m glad it didn’t disappoint.

Large alloy wheels – in particular the range of 22-inch designs – optimize the vehicle’s stunning silhouette, while further enhancing the dramatic presence of the vehicle.

His architects there are Foster + Partners, which is led by Norman Foster. Since 2009, the same firm—“Norman’s boys,” as Ive has sometimes put it—has worked on Apple’s new campus. Inevitably, Ive is a co-designer of his house; according to Cook, he is playing the same role with the new headquarters. Apple loves its architects, Cook said, but “you can’t outsource your brain.” The building should express “the way we look at the world.”

The Hitch Assist feature makes it easier to hook up the vehicle to the trailer. Using the surround cameras, the touchscreen displays the rear towbar and recognizes the trailer mounting point. The display then zooms in, showing a trajectory line, which responds to steering wheel inputs to help the driver to guide the vehicle into place2.
