Generally a solid first converts into a liquid and then into a gas. But under certain conditions of temperature and pressure, certain compounds turn directly to gas without passing through a liquid phase first. Answer and Explanation: When a solid is converted d...
The gas generated by a solid gas generator serves as primary energy source. For example, gas turbine engine, gas booster accumulator for the Sparrow series; gas turbine driven engine-hydraulic pump for the Aspide. 2. The gas generated by liquid gas generator is used as primary energy source....

to as “gas-to-wire,” or GTW, technologies); using compressed natural gas (CNG) that avoids the cost of gas liquefaction; converting gas, particularly associated gas, into solids or slurries formed of gas hydrates for storage and transportation (generically referred to as “gas-to-solid,” ...
Early simulation work adopted drag force closures directly from experimental data on fixed beds or homogeneously liquid–solid fluidized beds. In recent years several groups addressed the significance of drag reduction resulting from sub-grid level structures. O’Brien and Syamlal (1993) proposed an ...
